London attack: What we know

Saturday's rampage followed a suicide bombing that killed 22 adults and children at a pop concert in Manchester two weeks ago, and an attack in March when five people died after a auto was driven into pedestrians on London's Westminster Bridge.

They previously identified two other men as attackers: 27-year-old Khuram Sharzad Butt, a British citizen born in Pakistan, and 30-year-old Rachid Redouane, who "claimed to be Moroccan and Libyan".

In Saturday's attack, three men, wearing fake suicide vests, mowed down pedestrians on London Bridge in a van, before slashing and stabbing revellers in Borough Market, a haunt of late-night bars and restaurants.

Ms Stuart, who is co-head of the security and extremism unit at the Policy Exchange think tank, added: "The London Bridge attacker's connection to al-Muhajiroun's leadership raises very serious questions about the security services and the police".

A parliamentary election takes place on Thursday and May's spokeswoman said the government was working closely with police on security for the vote.

The Sun had previously revealed Khuram Butt made no secret of his extremist views, having appeared on a Channel 4 documentary The Jihadis Next Door a year ago.

Citing local media, The Daily Telegraph said the national was 27 years old and he worked in the Boro Bistro in Borough Market.

Unlike Butt, his accomplices were not known to the security services and are both thought to be foreign nationals.

"People are going to look at the front pages today and they're going to say: 'How on earth could we have let this guy or possibly more through the net?'", Johnson told broadcaster Sky News on Tuesday. The documentary has also been removed from Channel 4's webpage.

Mr. Khan said: "Not unreasonably, these questions are being asked". May has vowed to crack down on extremist content online, warning the public: "We cannot and must not pretend that things can continue as they are".

Prime Minister Theresa May, who called the snap election in hopes of strengthening her mandate for discussions over Britain's exit from the European Union, has come under fire for the cuts to police numbers over recent years.

The number of authorized firearms officers in England and Wales fell to just under 5,700 in 2016 from almost 7,000 in 2010.

Addressing the attackers, he said: "We will defeat you".

But the campaign focus switched abruptly from Brexit to social issues, to Corbyn's benefit.

A string of opinion polls over the past couple of weeks have pointed to a narrowing in the gap between her Conservative Party and the main opposition Labour Party.

THE uncle of the ringleader of the London Bridge attack has condemned the horrific massacre that claimed the lives of seven people.

It was the third attack in as many months where suspects had been on the radar of British authorities.

Praise has been heaped upon the police for their swift response and bravery.

May hit back by criticising Corbyn, a pacifist who has opposed some security legislation in parliament and expressed reservations in the past about police responding to armed attackers with "shoot-to-kill" tactics.

Police named Kirsty Boden, 28, an Australian nurse who lived in London, as one of the victims on Tuesday.

Following the attack, London Mayor Sadiq Khan said the threat level in the country is still "severe". Police were not yet releasing the names of the dead, but thousands of people gathered at Potters Field, across from the Tower Bridge and the medieval Tower of London, to pay tribute to the victims.

In what it said was an unprecedented move, the Muslim Council of Britain said more than 130 imams and other religious leaders had refused to perform the traditional Islamic funeral prayer for the attackers.
