London terror attack: Everything we know so far

At least seven people were killed and dozens more injured after a van drove into pedestrians on London Bridge and several men then started stabbing passersby in what police said was a terrorist attack.

The incident began on London Bridge when a white transit-style van drove into a crowd of people "at about 50mph", according to witnesses.

Police said the van then drove to the nearby Borough Market where three men began attacking people. Three suspects were shot dead by armed police.

Three men have been shot dead after killing seven and injuring 48 more with a van and knife attack in London.

The killings on Saturday night were the second terrorist atrocity to hit the country in as many weeks after 22 were killed at an Ariana Grande concert in Manchester.

Attackers brought carnage to the streets of the capital, stabbing a police officer and revellers with 12-inch knives, reportedly shouting "this is for Allah".

The trio were pictured wearing what appeared to be explosive vests, with Scotland Yard later confirming they were hoaxes.

Armed police rushed to the scene and shot dead the three male attackers in the Borough Market area near the bridge, as authorities urged Londoners on Twitter to "run, hide, tell" if they were caught up in the violence.

The attacks came just five days ahead of a national parliamentary election on Thursday. The ruling Conservative Party suspended national campaigning on Sunday, a spokesman for Prime Minister Theresa May 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," Ms May said in a statement as events unfolded.

The killings also occurred 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 BBC showed a photograph of two possible attackers shot by police, one of whom had canisters strapped to his body. Hours after the attack the area remained sealed off and patrolled by armed police and counter-terrorism officers.

The London Ambulance Service said 48 people had been taken to five hospitals across the city and a number of others had been treated at the scene for minor injuries.

Streets around London Bridge and Borough Market, an area that is a major transport hub and is packed with bars and restaurants, was busy with people on a night out.

London Mayor Sadiq Khan spoke of a "cowardly attack on innocent Londoners and visitors to our city enjoying their Saturday night".

Peter Rhodes, assistant director of operations at the London Ambulance Service, says: "Our thoughts are with all of those affected by the incident at London Bridge and their friends and family."He says the first ambulance crew were on the scene within six minutes of the first emergency call to them at 10.07pm. This means they were probably in the area before police shot the three suspects dead."We sent over 80 of our medics to the scene including ambulance crews, advanced paramedics, specialist response teams and an advanced trauma team from London’s Air Ambulance," Mr Rhodes adds."We declared a major incident and worked closely with other members of the emergency services at the scene. Our priority was to assess patients and ensure that they were treated and taken to hospital as soon as possible."
