LONDON - British police have named the three men who carried out the terror attack in London on Saturday - Khuram Butt, Rachid Redouane and Youssef Zaghba.
All three were shot dead by police after they drove a van onto the sidewalk of London Bridge, running over pedestrians, before jumping out of the vehicle and stabbing patrons at the bars and restaurants of nearby Borough Market. Seven people were killed and dozens injured in the attack.
The Islamic State in Iraq and Syria (ISIS) militant group has claimed responsibility for the attack.
Here's what is known about the suspects so far.
Khuram Shazad Butt, 27, was a British citizen born in Pakistan who appeared in a television documentary last year about extremists living in Britain.
He was investigated by police and Britain's domestic spy agency MI5 but police said that there was "no intelligence to suggest that this attack was being planned", Reuters reported.
In the documentary, Butt is featured along with a number of British Muslim men openly expressing their support for violence. In one scene, Butt stands in line with five other men in Regent's Park in London as another man kneels in front of them unfurling an ISIS flag.
The Guardian said Butt was a supporter of the banned Islamist group Al-Muhajiroun, which last month urged people in east London not to participate in the upcoming British general election.
Butt reportedly went by the name of Abu Zaitun, but was commonly known by his nickname Abs at the gym where he trained and the mosque where he worshipped, AFP reported.
Neighbours in his east London neighbourhood of Barking said he spoke with a heavy London accent. He was reported to be a big Arsenal fan - and was seen wearing the team's jersey during the attack.
Residents of the Elizabeth Fry Apartments on Kings Road said Butt lived in the building with his wife and two children - a boy and a baby girl. He has been spotted walking with his children.
Nasser Ali, who lives in the building facing Butt's apartment, told the New York Times: "His wife just gave birth, the baby was two weeks old."
Another neighbour Shehzad Khurram told the paper: "I just saw him going in and out (of the apartment complex)...I saw him walking with his kids."
Sarah Sekyejwe, who lives in the area, said Butt moved into the neighbourhood in 2014 and befriended the local children. "My daughter says he's the one who on Halloween would open the door and give them lots of sweets," she recalled. "And in the summer he put out a table-tennis table and taught the kids how to play."
Another of Butt's neighbours, Ken Chigbo, described Butt as someone whom he got along with. He said Butt had invited his neighbours to a barbecue just a week ago. "He invited me and everyone to a barbecue in the block's shared garden green area a week ago," Chigbo said. "He's a neighbour. I trusted him, we got on."
Chigbo recalled that Butt "would always be in a religious gown to his shins, with tracksuit bottoms and trainers underneath."
He added that small groups of three or four "Muslim guys" visited Butt's apartment regularly. "I found them quite intimidating, actually," he said. "They were always in religious robes and wearing red and white checkered scarves wrapped around their heads."
Michael Mimbo, 25, said he had known Butt for three years. He said he had seen the rental van used in the attack outside the Elizabeth Fry block on Friday. "The van he rented was here on Friday. It was blocking people from coming in. People were beeping their cars saying: 'Get out of the way'."
Mimbo said he saw the van again on Saturday at around 7.45pm - just over three hours before the attack. "The van was racing up the street with another red car behind it," he told The New York Times.
Mimbo said the two had spoken excitedly about the FA Cup final match between Arsenal and Chelsea on May 27. Butt, he said, was very happy when Arsenal won. "He was a calm and kind guy. It's unbelievable what's happened."
Rachid Redouane was 30 and had "claimed to be Moroccan and Libyan", the authorities said.
He also sometimes used the pseudonym, Rachid Elkhdar.
Ireland's national broadcaster RTE reported that Redouane had an Irish residency card and lived in Dublin as recently as three months ago.
He was not previously known to the authorities.
The Guardian said he was a pastry chef who had lived in Dagenham in east London, not far from where Butt was residing.
It said Redouane had married a British woman, a London-born care worker named Charisse O'Leary, in Ireland in 2012, and the couple had an 18-month-old daughter. O'Leary also went by the name of Charisse Redouane.
Despite the marriage, O'Leary never converted to Islam and the couple recently broke up, said a woman who knew the couple. They were said to have disagreed about how to raise their daughter.
According to the paper, O'Leary's recent posts on social media identified herself as single and she had lamented that Redouane had not been visiting his daughter.
O'Leary was one of the people rounded up by police in London on Sunday at a temporary accommodation centre near the Barking train station, The Guardian reported.
The third attacked named by police is an Italian-Moroccan who was arrested last year on suspicion of trying to reach Syria, according to Italian media reports.
Italy's main media outlets said Youssef Zaghba, 22, was the son of an Italian mother from Bologna and a Moroccan father.
The couple were separated and their son, who had passports from both countries, lived mainly in Morocco with regular periods spent working in Britain.
The Italian reports said Zaghba was intercepted at the Bologna airport last year as he was about to board a plane for Turkey, apparently with the intention of joining ISIS militants in Syria.
He was detained with only a small backpack, his passport and a one-way ticket to Istanbul.
Police reportedly found ISIS propoganda videos on his cellphone, but after an investigation, they failed to find sufficient evidence of links to terrorism to prosecute him.
As a result he was released, and being a holder of an Italian passport he was not liable for expulsion under the kind of administrative order Italy routinely uses against suspected Islamist militants from Morocco and Tunisia.
According to the reports, the British and Moroccan secret services were notified of Zaghba's status as a potential militant.
But British police said Zaghba was "not a police or MI5 subject of interest".
According to the reports, Zaghba was born in Fez, Morocco, and never lived for any extended period in Italy.
His mother told police last year that he had asked her for money to travel to Rome before he left on his abortive trip to Syria.
