The attack was launched on Saturday night, with terrorists running a van into pedestrians on London Bridge, and stabbing several people in Borough Market before being shot dead by police.

  • Seven people were killed in what London police are calling two "terrorist incidents" at London Bridge and Borough Market late Saturday night.
  • Police believe three suspects, who have yet to be identified, were involved and they have all been shot dead. No one has claimed responsibility for the attacks.
  • Armed police responded to a van reportedly running into pedestrians at London Bridge before suspects exited the vehicle and began stabbing individuals at Borough Market.
  • At least 48 people have been taken to five hospitals across the capital to be treated for their injuries. Some are in a serious condition. Some wounded were treated at the scene or at a rescue center set up in a hotel in Liverpool Street.
  • Police say a stabbing in Vauxhall was not related to incidents at London Bridge and Borough Market.
  • Campaigning for the U.K. general election has been suspended, with the Conservatives and SNP announcing they will not campaign today, and other parties expected to follow suit.
  • Prime Minister Theresa May has spoken outside Downing Street and vowed a new battle against Islamic extremists: "Enough is enough," she said.

Chris continued: "I turned around and tried, but he side-stepped me.

"I spun the cab round, I was about to ram one of them, but he side-stepped and three police officers came running towards them with their batons drawn, they didn't know what was happening.

"There was a guy with a really long blade randomly stabbing people. I told people to turn around and run away."

Chris said the attack sickened him "to the pit of my stomach."

Another taxi driver, Ashka Patel, told Sky News that a passenger had left his vehicle and managed to act as a barricade, preventing the attackers entering a restaurant.

Patel said she held the door for "a few seconds" befire being overpowered, allowing people to escape from the back entrance of the Black and Blue restaurant.

He said: "She knew they were bad people trying to break in."

"People managed to escape through the rear door possibly saving a good 20 people's lives."

Candice Hedge, 31, is one of the victims, reported the Courier Mail. According to the report she was having a drink in a bar with her boyfriend when an attacker came up behind her, grabbed her head, and slashed her throat.

She has reportedly woken from a coma and is now awake and talking to friends.

11.44 a.m. - Police and security services are recommending the threat level is not raised from its current level of "severe," meaning an attack is highly likely, to "critical," meaning an attack is imminent, Home Secretary Amber Rudd said in an ITV interview, following an assessment by the Joint Terrorism Analysis Centre (JTAC).

She said: "We don't believe there are additional elements which could be carrying on the attack last night. JTAC has made that assessment, so they haven't recommended going to critical. We can't be 100% sure, the police are still carrying on their operation, but if JTAC thought there were more people out there who could be extending this attack I expect they would have considered raising it. We're staying at severe because we think they have caught all the main perpetrators."

In the wake of the Manchester attack, the threat level was raised to "critical," as investigators did not know whether or not other people involved in the attack were still free and preparing further attacks.

11.03 a.m. - According to reports, police have conducted raids in an apartment block in Barking, east London. Sky News is reporting that the raids are linked to the attack. The Telegraph is reporting that five people have been arrested.

A Met Police spokesman told Newsweek the force was providing no information on the raids at this time, and would not confirm if they were linked to the terror attack on Saturday.

Witness Tara Milan, 24, told the Telegraph a suspect was shot by police trying to flee. Footage and pictures show an ambulance outside the block.

10.53 - May said that that "we are experinecing a new trend" in terrorism, with terrorists inspired to act by other attacks. She said that police and security services had disrupted five credible plots since the Westminster attack in March.

"Our country has made significant progress in disrupting plots and protecting the public," she said.

"But it is time to say enough is enough. Everybody needs to go about their lives as they normally would.

"Our society should continue to function in accordance with our values but when it comes to taking on extremism and terrorism things need to change."

Mrs May said that General Election campaigning will resume tomorrow and that polling day on June 8 will go ahead as planned.

The Prime Minister struck a tougher tone than in her speech after the Manchester attack, and said that "things need to change" in the fight against terror and that the UK "cannot and must not pretend that things can continue as they are" and plans to bring in longer sentences of terror offences and to review the Government's counter terrorism strategy.

She said the attacks are connected in "one important sense".

"They are bound together by the single evil ideology of Islamist extremism that preaches hatred, sows division and promotes sectarianism," she said.

"It is an ideology that claims our Western values of freedom, democracy and human rights are incompatible with the religion of Islam.

"It is an ideology that is a perversion of Islam and a perversion of the truth.

"Defeating this ideology is one of the great challenges of our time but it cannot be defeated through military intervention alone."

British police had rushed to an incident on London Bridge on Saturday after witnesses said a van ploughed into pedestrians. Police said armed officers were also responding to an incident in the nearby Borough Market area of the city.

One witness told Reuters that she saw what appeared to be three people with knife wounds at London Bridge. Another witness told the BBC she saw a speeding white van veering into pedestrians. That witness said the van hit five to six people. Reuters television pictures showed dozens of emergency vehicles in the area around London Bridge.

Several witnesses also reported hearing gunshots though police have not yet confirmed those reports.

London's transport authority said London Bridge rail station had been closed at the request of the police.

The incident comes days ahead of a June 8 election, with polls suggesting the lead of Prime Minister Theresa May's Conservative Party has dropped sharply.

It also comes less than two weeks after a suicide bomber killed 22 people at a pop concert by U.S. singer Ariana Grande in Manchester in northern England.

The Manchester bombing on May 22 was the deadliest attack in Britain since July 2005, when four British Muslim suicide bombers killed 52 people in coordinated attacks on London's transport network.
