A man who stabbed two people to death and wounded three others in a "terror-related" attack was shot dead by police on London Bridge after he was held down by members of the public.

Usman Khan, 28, had been released from jail on licence in 2018, half-way through a 16-year sentence for terrorism offences.

Cambridge University graduates Jack Merritt, 25, and Saskia Jones, 23, were killed in the attack.

The victims

Jack Merritt, studied law at the University of Manchester before going to Cambridge to continue his studies.

Saskia Jones, was from Stratford-upon-Avon, Warwickshire, and both were involved in a university prisoner rehabilitation programme at Cambridge University.

Mr Merritt, from Cottenham in Cambridgeshire, was a co-ordinator and Ms Jones a volunteer, the Met Police said.

They were attacked during a conference being held on Friday afternoon at Fishmongers' Hall, at the north end of London Bridge.

The family of Ms Jones paid tribute to her as a "positive influence at the centre of many people's lives".

Ms Jones' former university tutor Colleen Moore told BBC Breakfast: "She was fearless, she was a warrior, she was going to change the world - maybe she will."

"She was a lovely, lovely woman, she made me laugh. She called me out on things - a lot of people were scared of me, she wasn't."

Mr Merritt had a "deep commitment" to the scheme, known as Learning Together, according to people who worked with him.

His father David Merritt said his son was "a beautiful spirit who always took the side of the underdog".

A member of university staff was also among the three people injured.

Two of those, both of them women, remain in a stable condition in hospital, according to police.

What happened?

Khan's attack began at 13:58 GMT inside Fishmongers' Hall.

Fishmonger Company chief executive Toby Williamson said staff who fought Khan as he launched his attack believed he was wearing a bomb.

He described the scene inside the hall as a game of "pinball bomb with added knives".

He said one staff member in the hall's reception tried in vain to hold Khan back behind doors while another calmly placed a call to emergency services.

Mr Williamson said two men used chairs, fire extinguishers, a pole and a narwhal tusk, which was hanging on the wall, to fend off Khan after he broke through the doors, driving him out of the building.

One of those called Lukasz, a Polish national who was working as a porter in the hall's basement, suffered five wounds to his left-hand side as he fended off the knifeman with a pole during "about a minute of one-on-one straight combat" - allowing others time to escape danger, Mr Williamson said.

Lukasz was taken to hospital for treatment but has since been able to return home.

Khan was forced out of Fishmongers' Hall by a group of men - with hall staff joined by participants of the Learning Together conference - said to include ex-prisoners, probation and prison staff.

Two men can be seen in a video holding the attacker back using a whale tusk, seized from a wall mount, and a fire extinguisher spray, before others stepped in to pin him down.

In a second video a man is seen walking away holding a large knife they had retrieved. British Transport Police said later he was a plain clothes officer.

The Metropolitan Police said its armed officers arrived on the scene within five minutes of the initial 999 call.

The people holding Khan down were moved away by the armed police officers after they thought he was wearing a suicide vest under his jacket.

He was then shot by an officer.

The Met's assistant commissioner said the explosive vest which turned out to be a hoax looked "very convincing".

What do we know about the attacker?

Mr Basu said Khan was released from jail in December 2018.

He had been convicted in 2012 after plotting with a group from Stoke-on-Trent, London and Cardiff.

They discussed attacking the London Stock Exchange and pubs in Stoke, and setting up a jihadist training camp in Pakistan.

One of the conditions of his release was that he should wear an electronic tag.

He also had to take part in the government's desistance and disengagement programme, the purpose of which is the rehabilitation of people who have been involved in terrorism. The Parole Board said it had no involvement in his release from jail.

Usman Khan had spent years preaching in Stoke and had links to the banned organisation al-Muhajiroun.

What is happening now?

An urgent review of the licence conditions of people jailed for terror offences has been launched by the Ministry of Justice (MoJ).

It confirmed the number of offenders convicted of terrorism offences who are currently under supervision in the community is 74.

In a Twitter response to Brendan Cox, whose MP wife Jo Cox was murdered, Jack Merritt's father said: "I obviously don't have full facts about the process that led to the attacker being released but what I can say with certainty is that no one at the event had the slightest inkling that he could or would do something like this.

"We don't need knee-jerk reactions."

A vigil was held at the Guildhall Yard in London and outside the Guildhall in Cambridge on Monday.

Prayers have also been said at Southwark Cathedral for Mr Merritt and Ms Jones.

The Dean, the Very Revd Andrew Nunn, said the incident had brought back memories of the 2017 attack.

Officers have been carrying out two searches; in Stafford where Khan is believed to have lived, and in Stoke-on-Trent.

Mr Basu said police were going through at least 500 images and videos sent to them.

Police patrols across London have been increased as a result of the attack.

The Queen sent "thoughts, prayers and deepest sympathies to all those who have lost loved ones" on behalf of herself and Prince Philip.

Six people died, including the attacker, and at least 50 people were injured after a terror attack near the Houses of Parliament on 22 March. This is what we know about what happened that day.

What happened?

The attack lasted 82 seconds.

It began at 14:40 GMT when Khalid Masood drove a car - hired from a depot in Birmingham - over Westminster Bridge, near the Houses of Parliament.

One witness said he sped up, mounted the pavement, and began hitting pedestrians indiscriminately.

Police believe Masood was driving at up to 76mph.

14:40:08 - Masood's car mounts pavement on Westminster Bridge and hits pedestrians

14:40:38 - Masood crashes into perimeter fence of Palace of Westminster

14:40:59 - First 999 call made to Met police

14:41:30 - Masood leaves vehicle, runs towards Parliament, and is shot dead

The car then crashed into railings outside the Palace of Westminster.

Masood, armed with a knife, left his car and ran towards Parliament, where he was confronted by police.

PC Keith Palmer - who was wearing a protective vest but was not armed - was stabbed and killed. Masood was then shot dead by armed officers.

A 75-year-old man, Leslie Rhodes from Clapham in south London, died from his injuries the next day and Romanian Andreea Cristea, who fell from Westminster Bridge into the River Thames, died more than two weeks later.

Who was the attacker?

Khalid Masood, 52, was born in Kent on Christmas Day 1964. Before the March attack he was believed to have been living in the West Midlands.

He had a criminal past but his most recent conviction, for possessing a knife, was in December 2003. He had never been convicted of a terrorism offence.

Speaking shortly after the attack, Prime Minister Theresa May told MPs that while Masood had been "once investigated in relation to concerns about violent extremism" he was a "peripheral figure" and "not part of the current intelligence picture".

After his birth, Masood was registered in the Dartford district of Kent, but his name was given as Adrian Russell Elms.

Two years later, his mother married a man with the name Ajao and, as a child, Masood was known as Adrian Russell Ajao. He later used both Ajao and Elms until he converted to Islam and became Masood.

Masood spent a number of years working in Saudi Arabia teaching English as a second language at the General Authority of Civil Aviation in the port city of Jeddah, the BBC understands.

He gave his occupation as "teacher" when hiring the car he used to carry out the attack.

However, the Department for Education said it had no record of him having worked as a qualified teacher in English state schools.

Masood is believed to have had at least three children.

Who were the victims?

The police officer who died was PC Keith Palmer, 48, of the parliamentary and diplomatic protection command. He had 15 years' service, was married, and had a five-year-old daughter. He had served in the Royal Artillery before joining the police.

Aysha Frade, who worked in administration at DLD College London, was killed after being hit by the attacker's car before it reached Parliament.

She was 44 and a married mother of two young daughters.

The third victim was Kurt Cochran, 54, from Utah, who was in London to celebrate his 25th wedding anniversary. His wife Melissa was seriously injured.

Leslie Rhodes, 75, a retired window cleaner, had been receiving medical treatment in hospital following the attack. His life support was withdrawn on 23 March.

Romanian Andreea Cristea, who was on holiday with boyfriend Andrei Burnaz, died on 6 April as a result of her injuries. She had been in hospital since the attack.

Her family said in a statement: "After fighting for her life for over two weeks, our beloved and irreplaceable Andreea - wonderful daughter, sister, partner, dedicated friend and the most unique and life loving person you can imagine - was cruelly and brutally ripped away from our lives in the most heartless and spiritless way.

"She will always be remembered as our shining ray of light that will forever keep on shining in our hearts."

Who are the injured?

At least 50 people from at least 12 countries were injured in the attack, 31 of whom needed hospital treatment.

Among those injured were three police officers who had been walking across Westminster Bridge on their way back from a commendation ceremony.

PC Kristofer Aves was one of two described as having "very significant" injuries.

Acting Deputy Commissioner Mark Rowley said the victims represented "a real cross-section of ages". As well as Britons, there were people from France, South Korea, Greece, Germany, Poland, the Irish Republic, China, Italy and the US.

Among others injured were four university students from Edge Hill University, in Ormskirk, Lancashire.

Seven men and five women aged between 21 and 58 were arrested in London, Birmingham and Manchester under the Terrorism Act - but all were later released with no further action.

Acting Deputy Commissioner Mark Rowley said 2,700 items had been seized, including "massive amounts" of computer data.

Masood's phone is understood to have connected with WhatsApp two minutes before the attack, but the messaging app's encryption system means police may not know what if anything was communicated.

The Hyundai driven by Masood had been hired in Spring Hill, Birmingham, from a branch of Enterprise.

Police were contacted by about 3,500 witnesses - 1,000 who were on Westminster Bridge and 2,500 who were within the Parliamentary estate at the time.

Hundreds of videos and pictures have been uploaded to the NPCC website, Mr Rowley added.

On 25 March, Deputy Assistant Commissioner Neil Basu said detectives believed Masood had acted alone and that there was no information or intelligence to suggest further attacks were planned.

"There is a possibility we will never understand why he did this," he added.

He said that while Masood "clearly had an interest in jihad", police had so far found no evidence of an association with the so-called Islamic State group or al-Qaeda.

This story was updated on Friday 7 September, 2018, ahead of the start of the victims' inquests.

Questions continue to be asked about whether Wednesday's fatal terror attack in Parliament could have been prevented if more officers had been armed.

Attention is focusing on how Khalid Masood was able to enter the Carriage Gates entrance of Parliament before he was confronted and subsequently shot.

One security expert said the breach may have been a product of complacency.

Ministers insist the police did their job and Parliament can't be sealed off - and a security review is under way.

A Parliamentary spokesman said security was always under "constant review" but the building had to remain "open and accessible" for it to function.

The review follows the fatal stabbing of PC Keith Palmer in the grounds of the Palace of Westminster.

Ministers have declined to comment on unconfirmed reports that his alleged assailant was shot dead by a member of Defence Secretary Sir Michael Fallon's close protection team, who happened to be at the scene, rather than a uniformed officer stationed at the gate.

Some MPs regard the carriage gates entrance, which is used by government cars to drop off and pick up ministers, as a weak point in the security perimeter.

It is manned by two police officers but they are not always armed and the gate is often open, unlike other entrances to the Palace of Westminster.

The Times reported that a 2005 review had found the entrance to be a weak point, primarily due to the number of delivery vans using it.

The paper quoted parliamentary sources as saying any changes at the time had been regarded as "too cumbersome".

'Not intrusive'

The Met Police said the current security arrangements had been in place for many years and were "designed to provide access to the seat of our government balanced carefully with security that is proportionate but not overly intrusive".

"Of course, after an incident like this, as would be expected, my team will work with parliamentary authorities to assess whether a different tone or a different balance is necessary," Assistant Deputy Commissioner Mark Rowley said on Friday.

Parliament, which oversees its own security, said the arrangements should reflect the level of risk it faced.

"As is good practice following any significant incident, the Houses in conjunction with the police and other bodies will also be carrying out a review of security around this specific incident," a spokesman said.

Former Northern Ireland Secretary Theresa Villiers has said there is now a case for all police officers guarding Parliament and other "sensitive sites" to be routinely armed.

How Parliament is policed: By the BBC's Jack Evans

There are two Metropolitan Police officers manning Carriage Gates at all times.

Behind the gates there is a hut staffed by a third officer, whose job is to monitor pedestrians exiting the estate.

All three officers are issued with stab vests.

They check to ensure the driver of a vehicle or bicycle has the correct parliamentary pass. Cars are security vetted beyond the gates. They all have two way radios so can call for help in emergencies.

Armed police are on patrol throughout the Parliamentary estate at all times but they are more visible at times of heightened security.

Security expert Professor Anthony Glees said the attack had demonstrated a "lack of protection" within Parliament.

"I am very disturbed by the complacent attitude," Prof Glees, who heads the Centre for Security and Intelligence Studies programme at the University of Buckingham told the BBC's Victoria Derbyshire programme.

"The fact is in immediate terms and wider terms, this was a failure of security policy.

"This is someone who got within 100 metres of where the prime minister was. If he had an explosive vest, we would be having a very different conversation."

'No panacea'

Tony Long, a former armed police officer, said those stationed at College Gates were effectively "meeters and greeters and pass checkers" who were well known to MPs.

He told Victoria Derbyshire there had been a huge reluctance within Parliament, which oversees its own security, to have armed officers on patrol.

"There is a huge amount of tradition about that building," he said.

"I guarantee if those gates were shut, the first person to complain about it would be an MP or a cabinet minister."

Several MPs have warned Westminster should not be turned into a fortress.

"The idea that arming all police will be a panacea and a solution to this problem may well be mistaken," said Conservative MP Dominic Grieve.

"It is worth bearing in mind that in fact security wasn't breached. There was a tragic loss of life but in trying to breach security, he was stopped."

Kim Howells, a former chair of the Intelligence and Security Committee, said one must remember Parliament is a "working building with people moving in and out".

Asked why Masood had not been stopped from entering the parliamentary estate, he said: "This guy ran in through the gates. As a former rugby man, I know it is not easy to bring down a man in such a situation."

There was a major review of security at the Palace of Westminster in 2014 which was supposed to "assess the strengths and weaknesses of the current arrangements and to make recommendations". Its findings have not been published.

Twenty-two people were killed and 116 injured in a suicide bombing at Manchester Arena.

Here's what we know about the attack so far.

What happened?

Attacker 22-year-old Salman Abedi detonated a home-made bomb in the arena's foyer as crowds were leaving a performance by US singer Ariana Grande just after 22:30 BST on 22 May.

The blast, between the main arena and neighbouring Victoria station, blew people off their feet and caused widespread panic. Witnesses described hearing an explosion and seeing a flash of fire.

Pictures of the aftermath show debris and casualties in the foyer area of the arena. Metal nuts and bolts were strewn around the floor among bodies. The smell of explosives was in the air, witnesses said.

How did people escape?

The bomb was detonated moments after Grande had performed her final song and fans had started making their way home.

People began scrambling for the arena's exits and were seen fleeing down the stairs from the foyer into the station.

People who had arrived to drive friends and relatives home were forced to go on a desperate hunt to find missing children.

More than 240 emergency calls were made; 60 ambulances and 400 police officers attended.

What happened in the foyer?

The foyer where the bomb went off is the busiest exit from the arena - housing the box office and leading to the car park and Victoria Station.

Photos from the scene have been leaked to the US media.

According to the New York Times, analysis of images of the scene reveal how the bomb's shrapnel penetrated metal doors and left marks on brickwork.

The paper said the authorities' review of the blast site shows the bodies of those killed were located in a circle around where the device was detonated - just outside the arena's main exit.

The photos also appear to show bloodstained fragments from the bomb and the backpack used by the attacker.

The images show the remains of a Karrimor backpack, a possible detonator, a 12-volt battery as well as metal nuts and screws.
Who carried out the attack?
Salman Abedi, was named by police as the suicide bomber shortly after the attack.

Abedi was one of three siblings and was born in Manchester on New Year's Eve 1994.

The family, of Libyan origin, lived at several addresses in Manchester, including properties which were raided by police.

Abedi attended Burnage Academy for Boys in Manchester between 2009 and 2011, before going to The Manchester College until 2013 and then Salford University in 2014.

BBC News was told the public called an anti-terrorism hotline after he expressed the views that "he was supporting terrorism" and "being a suicide bomber was ok", but Greater Manchester Police said it has not found any records of these calls taking place.

Abedi was arrested for minor offences in 2012 but was not known to the government's Prevent scheme.

It was later revealed that MI5 is to hold an inquiry into the way it dealt with warnings from the public that Abedi had expressed extremist views and was a potential threat.

Abedi left the UK on 15 April and travelled to Libya before returning back into the UK on the 18 May, the police investigation has found.

The so-called Islamic State group has claimed responsibility, but this has not been verified.

Victims named

All 22 victims have been named. The youngest victim to be named is eight-year-old Saffie Roussos, from Leyland, Lancashire.

Elaine McIver, an off-duty officer from Cheshire Police, was also among those killed. She was with her partner, Paul, and two children, all of whom were injured.

In total, 116 people were admitted to hospital in relation to the attack, NHS England said.

Sixty three people are still being treated in eight hospitals, including 23 patients who are in critical care.

The investigation

Twenty-two people have been arrested in the UK in connection with the attack, all of whom have now been released without charge.

Those arrested included Abedi's older brother, Ismail, 24, who was detained in Whalley Range the day after the bombing.

Abedi's younger brother Hasham, 20, was detained in Tripoli on suspicion of links with the so-called Islamic State group the day after the attack.

Reuters news agency told the BBC that Abedi's father, Ramadan, had also been detained in Libya.

The bomber's two cousins, Isaac and Abz Forjani, were both arrested the day after the attack and questioned by police for seven days.

The pair said Abedi had never admitted extremist views, and thought he may have been radicalised abroad.

On 23 May, police raided a flat in Granby Row, Manchester, that Abedi may have used before the attack on Monday night.

Twenty-nine house searches have been conducted by police.

Officers have examined Abedi's movements on CCTV and other interactions he had with people as well as phone calls he made.

Police have yet to rule out whether he was part of a wider network, although it is thought most likely that Abedi assembled the bomb himself.

It is less clear whether he acted alone in buying the components needed to make the device.

Police believe Abedi wanted to carry out the attack within days of returning to the UK after a month-long trip to Libya.

CCTV has shown him purchasing more items for the bomb soon after he arrived back, including buying nuts from a DIY store that were used for shrapnel as well, said Russ Jackson, head of the North West counter terrorism unit.

Abedi was also tracked going to and from the Banff Road area of Rusholme, where a white Nissan Micra was found.

The Micra - which was bought on 13 April - contained materials for bomb making and Abedi is forensically linked to the car, say police.

Detectives believe items were stored in it for a short period of time, either material to make a bomb or a pre-made charge. The actual assembly of all the parts appears to have been in the days immediately before the attack.

Police have appealed to the public for information relating to the car's movements on 14 April. They also released images of plastic barrels stored in the Nissan.

Meanwhile a search is ongoing at a landfill site for a blue suitcase thought to contain items Abedi discarded after having assembled the device.

Hashem Abedi left the UK at the same time as Salman on 15 April. He is currently detained in Libya, but British police have said they wish to interview him in relation to the attack.

Shortly after the bombing, police investigating the attack temporarily stopped sharing information with the US after leaks to the media.

UK officials were outraged when photos appearing to show debris from the attack appeared in the New York Times.

Anyone with information can call the anti-terror hotline on 0800 789321.

The police have also appealed to anyone with images or footage from the attack to upload it to ukpoliceimageappeal.co.uk or ukpoliceimageappeal.com

Extra security

After the attack, the UK terrorism threat level was raised from "severe" to "critical" for the first time since 2007.

The change indicated an attack was imminently expected.

Members of the armed forces replaced armed police at certain "key sites".

Home Secretary Amber Rudd said 984 servicemen and women were deployed as part of Operation Temperer - the government plan to put soldiers on the streets.

This freed up extra armed police officers for deployment at sporting events over the bank holiday weekend, including the FA Cup final.

Sporting events and venues in England also conducted major security reviews. Chelsea FC cancelled their Premier League victory parade.

Police Scotland said it was reviewing all "significant events" taking place within the next 14 days and increased the number of armed police on patrol.

The threat level was reduced to severe after a meeting of the government's emergency committee Cobra on 27 May.

Marauding terrorist attacks (MTA) are fast-moving, violent incidents where assailants move through a location aiming to find and kill or injure as many people as possible. Most deaths occur within the first few minutes of the attack, before police are able to respond.

MTAs can take many forms and include a combination of the following:

A lone attacker, multiple attackers or multiple groups of attackers

Arrival at a location on foot, in a vehicle or an attack perpetrated by insiders

Entering without using force or forcing entry using an explosive device, a vehicle, coercion of someone with access or a combination thereof

Attackers armed with bladed weapons, firearms, pipe bombs, petrol bombs suicide vests or multiple weapons

Bladed weapon attacks progress less rapidly than those involving firearms since attackers must be within striking distance of their victims and expend more energy on each person.

It is more important than ever that your organisation is aware of the heightened risks and adequately prepared for any potential attack.

New and detailed guidance is now available providing information as to the range of measure that can be taken to minimise the impact of an attack and help save lives. These measures range from implementing simple changes to security processes and technical systems to introducing new and sophisticated security systems.

Marauding terrorist attacks: Making your organisation ready discusses how your organisation can recognise an attack, take immediate action and facilitate the police. It is most relevant to office buildings, including multiple tenancy buildings. However, the principles of the advice can be usefully applied to all types of locations including cinemas, hotels, hospitals, schools, shopping areas, shopping centres, stadiums, theatres, temporary event venues and transport hubs.

Basis of the guidance

The guidance has been written and based on:

Extensive analysis of previous MTAs in the UK and elsewhere around the world

Live simulations of marauding attacks involving hundreds of people to understand where responses can fail and test the effectiveness of training, procedures and security systems.

Reviews and discussions with businesses that have highlighted common issues.

Introducing the MTA Guidance

CPNI and NaCTSO have developed a series of guides to help your organisation assess the risk and implement a range of protective security mitigations. These guides are based on analysis and learning from MTAs that have taken place, live simulations of attacks and exercises and feedback undertaken with businesses.

The 10 guidance pieces are:

MTA: A Busy Reader's Guide to Making Your Organisation Ready, which provides a high level summary of the key issues for senior managers.

MTA: Making your organisation ready, which is the principal guidance document setting out all of the protective security mitigations and considerations

MTA: Technical supplements, providing further information of specific topics that are important to effective defences.

These are:

Announcements - alerting personnel using live and recorded announcements

Lockdown - considerations for locking doors to delay and frustrate attackers

Physical Barriers to Delay and Discourage Attackers - making the best use of low security features, such as doors.

Active Delay Systems - measures that can further delay the rate of progress of an attack

Preparing personnel - developing a programme to raise awareness and provide training to staff

Working with police and other emergency services - integrating your response with the emergency services and background on the emergency services' response to an MTA

Testing and Exercising - detailing techniques to validate that your plans will work at the moment of need.

ASCEND: Improving organisational response to marauding terrorist attacks - a summary of key emerging themes from trials conducted between 2017 and May 2018

This guidance also contains checklists contained in the documents, to help you establish next steps.

This is a video made by the Metropolitan Police Force, which highlights 'Operation Fairway' which teaches people that if something does not look right or seems suspicious then it must be reported if you genuinely believe that there is a risk of a possible terror attack.

For example, if someone has been travelling and their views have become a lot more radical, the content that they have been viewing, suspiciously watching the police movements or taking pictures of restricted areas in public places, taking pictures of fire exits and CCTV cameras.
