The 27-year-old known as “Abz’’ is believed to have been born in Pakistan but raised in Britain and was apparently radicalised by watching YouTube videos of the Arab-American hate preacher Ahmad Musa Jibril.

On Saturday night, Abz and two other jihadists launched a deadly attack with a car and a knife, killing seven people and wounding 48 more in a rampage through London Bridge and the Borough Market.

The three jihadists, wearing fake suicide bomb vests, were shot dead by police eight minutes after receiving a call for help.

Islamic State has claimed responsibility for the attack, the third in the UK in less than three months, saying through its Amaq propaganda outlet it had been carried out by one of its “sleeper cells.’’

“A security unit of Islamic State fighters carried out the London attacks yesterday,” it said.

VIDEO EMERGES OF POLICE SHOOTING TERRORISTS

The latest revelations came as new video emerged of the moment the three terrorists were gunned down by police.

The footage obtained by Sky News was shot inside Borough Market. In the video gunshots can be heard ringing out before panicking pubgoers sprint past, The Sun reports.

The man’s voiceover can be heard over the footage saying: “I’m direct from a terrorist attack in the middle of London.

The man goes on: “I just saw two guys getting shot. There’s another gunfire.

“I have no idea what’s going on, I can’t see from here.”

A police officer then runs past and shouts “you need to move” before pubgoers begin sprinting past.

It also emerged that an American bystander was shot in the head by police after they unloaded an “unprecedented 50 rounds” at the rampaging terrorists.

Fabio Lamas, who works at a pub in Borough Market, told NBC he saw “an American guy get shot in the head.”

Mr Lamos said: “He was bleeding through his eye. I went to get the first-aid kit and I started speaking to his friends and to try and calm them down.”

TRUMP TAKES ANOTHER JAB AT LONDON MAYOR

Meanwhile, US President Donald Trump has taken another jab at London Mayor Sadiq Khan over his reaction to the attacks.

Mr Trump accused Mr Khan of making a “pathetic excuse” over one of his comments in the wake of the attack that killed seven people in London.

Mr Khan had said in one of his first statements in reaction to the attack that people would see an increased police presence on the streets of the capital and should not be alarmed by that.

“Pathetic excuse by London Mayor Sadiq Khan who had to think fast on his ‘no reason to be alarmed’ statement. MSM is working hard to sell it!” Mr Trump said in a tweet on Monday. MSM referred to mainstream media.

Mr Trump had faced a barrage of criticism on Sunday over an earlier Tweet attacking Mr Khan.

A spokesman for Mr Khan, responding to Trump’s latest tweet, said: “Nothing has changed since yesterday.

“The mayor is focused on dealing with Saturday’s horrific and cowardly attack and working with the police, the emergency services and the Government to keep London safe.”

MAY UNDER PRESSURE OVER POLICE CUTS

Meanwhile, the revelations that at least one of the attackers was known to authorities will heap further pressure on Britain’s security forces, which has already confirmed the perpetrators of the two previous terror attacks were known to them before they launched their deadly attacks.

It will also raise difficult questions for Prime Minister Theresa May, a former Home Secretary for six years with responsibility for police resourcing, with the UK general election on Thursday.

It was revealed last month that UK spy agency MI5 had identified 23,000 “subjects of interest’’ living in the UK, of which 3000 were being looked at as part of 500 active investigations.

As 36 of the London Bridge victims remained in hospital last night, it was revealed 21 of them were fighting for their lives in a critical condition.

Canadian woman Christine Archibald was the first victim identified, with her family mourning their “beautiful’’ daughter and sister, who died in the arms of her fiance Tyler Ferguson after she was run down by the terrorists’ van on London Bridge.

Tyler’s brother Mark told British Columbia TV station CBC that the pair were based in Den Haag in the Netherlands, where Tyler works as an accountant. Work had taken him to London for a week and Ms Archibald decided to join him for the weekend.

A Spanish man is still missing after he used his skateboard against one of the jihadists, who was stabbing a woman, Spanish media report. Joaquin Echevarria, father of Ignacio Echevarria, 39, told EFE that UK police had asked for a copy of his son’s fingerprints in order to see if he was among the unidentified victims who are in hospital, as he was listed neither as injured nor dead.

Ignacio, originally from the town of Las Rozas near Madrid, was last seen on London Bridge on Saturday night.

His family said he was riding his bike back from skateboarding at the park with friends when he saw one of the assailants rushing towards a woman. “At that moment he launched himself towards the attacker and hit him with a skateboard while the other two injured him from behind and he was left lying on the floor,” they said.

A 27-year-old Frenchman, identified only as Alexandre, from Saint-Malo in Brittany, was also reported to have died after being stabbed at the Boro Bistro where he worked on Borough High Street.

“The bar was packed. A terrorist arrived and jumped from above onto a parasol on the terrace, injuring one of my colleagues,” said Vincent Le Berre, the bistro’s manager, according to the account his mother gave newspaper Le Télégramme in his native Brittany.

“He immediately started attacking people. A woman customer was killed. I found myself face-to-face with the terrorist who was two metres from me. I saw the hatred in his eyes. I managed to escape but my friend Alexandre wasn’t so lucky. He was stabbed in the neck with a knife,” he said, according to Vincent’s mother, Marie-Jo Le Berre, who had spoken to her son on the phone.

Prime Minister Malcolm Turnbull revealed “very real concerns’’ for another two Australians affected by the attacks, including 21-year-old Sara Zelenak, from Brisbane, who was last seen on London Bridge.

“She got separated from her friends and has not been seen since. Her phone has rang with no reply and now the battery must have gone,” a now-deleted Facebook post by family friend Diane Winter said.

Chilling video emerged of two of the men walking down Stoney Street after leaping out of their rented van and attacking people with large knives.

And police confirmed they had unleashed around 50 bullets on the terrorists when they confronted them in Stoney Street eight minutes after receiving the first 999 call, killing all three, and accidentally shooting a bystander in the head. The bystander is expected to make a full recovery.

Neighbours recognised Abz, a former employee on the London Underground train network, after they saw photographs of him dying in the street, wearing a fake explosive vest.

Police arrested 12 people after raids in Barking, in East London. Eleven people were detained at what is thought to be Abz’s flat, which he shared with his mother, his wife and two small children. They include six women aged 19-60. A woman, 38, was arrested at another address in Barking after police blew the door off the flat, and a 55-year-old man was arrested but released without charge.

Police have also raided properties in East Ham and Newham. Last night, police said 11 people, seven women and four men, were still detained.

A friend told BBC’s Asian Network that he had phoned the anti-terror hotline about Abz.

“He used to listen to a lot of Musa Jibril (notorious US hate preacher Ahmad Musa Jibril). I have heard some of this stuff and it’s very radical,’’ the neighbour said.

“I phoned the anti-terror hotline. I spoke to the gentleman. I told him about our conversation and why I think he was radicalised.”

The neighbour said Abz was not arrested and was allowed to keep his passport.

“I did my bit, I know a lot of other people did their bit, but the authorities did not do their bit.”

Another neighbour, Erica Gasparri, told the British media she had taken photos of Abz and provided them to police two years after he told her he was “ready to do whatever I need to do in the name of Allah’’ when she confronted him about trying to convert children in a local park to Islam.

Abz had previously appeared in a TV documentary about jihadism and was spoken to by police after an IS flag was unfurled, on camera, in a park.

Metropolitan Police Chief Commissioner Cressida Dick said last night police had been arresting “about one person a day’’ on terrorism offences.
