London Bridge attack - everything We know

Seven people have been killed and 48 injured, many of them stabbed, following a confirmed terrorist attack at two sites in London - London Bridge and Borough Market.

A van drove into pedestrians on the bridge and the three men stabbed people in both sites, with at least two eyewitnesses hearing them shouting: "This is for Allah".

The three attackers were shot and killed - dying within eight minutes of the first call, police said. Eight armed officers fired 50 rounds - "an unprecedented amount," according to Scotland Yard.

They believed all three were wearing suicide vests, which ultimately turned out to be fake.

Police said that they believe there are no more attackers on the run.

How did it start?

At 10.08pm police responded to a call about a white van ramming into five or six people on London Bridge.

The van reportedly veered off the road and drove into people on the pavement.

Paramedics were on the scene six minutes later, the London Ambulance Service said.

Police are piecing together eyewitness accounts, and believe that three men got out of the van and started attacking people with knives.

An eyewitness, Eric, told the BBC that he heard shouts of "this is for Allah".

John Stokes, a bus tour guide, said that he and the driver counted eight people lying on the road.

The three men then ran down to Borough Market.

What happened in Borough Market?

The three men appear to have stabbed people at random in the market.

They rampaged through the area, entering the many pubs and restaurants to stab anyone in sight

Crowds in the bars fought back - hurling pint glasses, bottles and chairs at the attackers.

One woman was stabbed repeatedly, according to a man named Gerard, who was trying to drive the attacker away by hurling chairs at him.

A security guard who works across multiple bars and pubs in Borough Market told the BBC he saw the attackers after receiving a call from a colleague in another bar who said people had been stabbed.

The security guard described people running away screaming from three men. He and his colleagues tried to throw chairs at the attackers, who were going in and out of different bars.

Within eight minutes police were on the scene and opened fire, killing the three attackers.

Photos on social media showed two of the men on the ground. One of them, in front of the Wheatsheaf pub, had what appeared to be canisters strapped to his abdomen.

Police later said that the canisters were fake.

Another eyewitnesses said she saw police and two robots - she speculated that the robots could be there to disarm the canisters.

Speaking outside New Scotland Yard, Met Commissioner Cressida Dick gave details of how the incident unfolded.

"Our officers confronted the suspects and brought this terrible incident to a conclusion within eight minutes," she said.

"We were called at 10.08pm last night initially to reports that a vehicle had struck pedestrians on London Bridge.

"That vehicle continued to drive from London Bridge to Borough Market. The suspects then left the vehicle and a number of people were stabbed.Loud explosions were heard in the vicinity - the most recent, a fourth, at 1:49am.The noises are believed to have been controlled explosions, carried out by police.

What do we know about the perpetrators?

Police now believe there were three attackers.

All three are dead - shot by police.

Eyewitnesses said one of the men appeared at first to be alive, but the other was not moving.

We do not yet know any details about their identities.

Police are undoubtedly going to be looking for associates and accomplices, but they do not believe that there are any more attackers on the loose.

What do we know about victims?

Police say at least six people have been killed.

It is not clear how many died on London Bridge, when the terrorists' van ran into people and the men then stabbed anyone nearby, and how many died in Borough Market.

Authorities say 48 people have also been injured; among them a transport police officer, a pub security guard, and a woman whose face and neck were bleeding profusely.

French foreign minister Jean-Yves Le Drian has told radio station FranceInfo four French citizens were injured in the attack.

It was previously reported there were two French victims.

Two Australians were directly affected, Prime Minister Malcolm Turnbull said.

One of the victims was confirmed to be in hospital, while Australian authorities were working to determine the status of the second person, Turnbull told at a news conference on Sunday.

Walking wounded were treated at the Andaz Hotel, near Liverpool Street.

The London Ambulance Service have confirmed that multiple crews attended both sites - London Bridge, and Borough Market.

THE SAFETY CHECK

What is safety check?When Safety Check is activated, users who Facebook determines to live or spend a lot of time in the affected area are sent a push notification asking if they want to check in as safe.They can then either check in or say the alert does not apply to them. Those that check in will send a notification to friends confirming they have been marked as safe.On the page itself, concerned users can prompt their friends to check in as safe. If they do not want to do this the page will also display when a user has last posted.Users in the area are also able to offer their help to anyone in need. Finding the safety check page on the Facebook app lets people "provide help" such as food, shelter and transport.The social network first introduced it in 2011 but until 2015's Paris attacks it had been used only for natural disasters.

What are Londoners being told?

The advice given was to keep calm, but make your way home.

The Metropolitan Police issued instructions to "run, hide, tell" - telling Londoners to get out of the area if possible; hide and silence their phones if not; and call 999 if safe to do so.

People are still being told they should avoid the London Bridge and Borough Market area, and only call 999 in an emergency.

Witnesses describe seeing a speeding vehicle veer into crowds on London Bridge and people being stabbed in Borough Market, central London. Seven people are killed and 48 injured. Police shoot dead three attackers within eight minutes of the first call. Both incidents are declared as terrorist-related.

Assistant Commissioner Mark Rowley of the Metropolitan Police said: "At this stage, we believe that six people have died in addition to the three attackers shot dead by police. And at least 20 casualties have been taken to six hospitals across London.

"We believe three people were involved but we still have some more inquiries to be 100% confident on that."

Where is the prime minister?

Theresa May will chair a Cobra meeting first thing on Sunday morning.

She said: "Following updates from police and security officials, I can confirm that the terrible incident in London is being treated as a potential act of terrorism.

"This is a fast moving investigation. I want to express my huge gratitude to the police and emergency services who are on the scene. Our thoughts are with those who are caught up in these dreadful events."

It is understood that the Prime Minister was in her Maidenhead constituency when she was alerted to the news.

So-called Cobra meetings are named after Cabinet Office Briefing Room A, where crisis response meetings are held. They usually include the Prime Minister and senior cabinet ministers as well as intelligence and security officials.

Mrs May held two Cobra meetings in one day less than two weeks ago on the day of the Manchester bombing.

Did the police have any warning?

The BBC security correspondent, Frank Gardner, is reporting that the police were not aware of any specific threat.

He says that the attack is being handled by the police, rather than the intelligence services, which means that there was no real warning.

Britain's official terror threat had recently been lowered from "critical" after a bombing killed 22 people at an Ariana Grande concert in Manchester.

But police were well aware that the bombing by Salman Abedi could spark another attack.
