At least seven people were killed by militants who drove a van at high speed into pedestrians on London Bridge and then stabbed revellers in the nearby Borough Market area on Saturday. 

All three attackers were shot dead by police. Forty-eight injured people were taken to hospital. 

The following is what is known so far:

- ISIS claimed responsibility for the attack, the militant group's agency Amaq said on Sunday. 

- One French national has died in London attack, France's foreign minister said Sunday.

- Assistant Police Commissioner Mark Rowley said police are confident that the three men fatally shot by officers in the minutes after the assault were the only attackers, but there is "clearly more to do" in the investigation. Security cordons will remain around London Bridge indefinitely.

- London’s assistant police commissioner says eight police officers fired “an unprecedented number” of bullets at the three men suspected of carrying out the attack on London Bridge and at nearby restaurants.

Assistant Police Commissioner Mark Rowley said during a news conference on Sunday that the officers fired 50 rounds at the men, striking and wounding a member of the public in the process.

- A Canadian national is among the seven people who were killed by three attackers who drove a van at pedestrians and stabbed others in the London Bridge area of London, Canadian Prime Minister Justin Trudeau said on Sunday. 

"Canada strongly condemns the senseless attack that took place last night in London, United Kingdom, which killed and injured many innocent people. I am heartbroken that a Canadian is among those killed," Trudeau said in a statement. 

- France’s minister for Europe said that four French citizens are among the dozens of wounded in the London terror attack that killed seven people.

Marielle de Sarnez expressed her condolences to the families affected and “absolute solidarity” with the British in a statement on Sunday.

- British police said they have arrested 12 people in east London over the attack in the London Bridge area.

Police said in a statement that the arrests were made Sunday morning in Barking by counterterrorism officers.

- U.S. President Donald Trump lashed out at London Mayor Sadiq Khan on Sunday, after the mayor urged city residents to remain calm following a deadly terrorist attack in the British capital. 

"At least 7 dead and 48 wounded in terror attack and Mayor of London says there is "no reason to be alarmed!"" Trump tweeted, several hours after promoting his controversial travel ban as an extra level of security for Americans in light of the attack.

- Prime Minister Theresa May chaired Britain's "COBR" emergency response committee in a meeting involving intelligence and security chiefs as well as senior ministers and officials. 

She then said the recent U.K. terrorist attacks are not connected, but their perpetrators are bound by the "evil ideology" of "Islamist extremism." She detailed four ways the U.K. should fight this extremism. 

- Three attackers drove a white van at high speed into pedestrians walking on London Bridge, police said. 

A witness told Reuters that at least six people were hit on the bridge. 

"It looked like he was aiming for groups of people. I froze because I didn't know what to do," Mark Roberts, a 53-year-old management consultant, told Reuters. "It was horrendous." 

Police said they responded to the incident on London bridge at 10:08 P.M.

- The men armed with knives left the vehicle and attacked people in the nearby Borough Market area on the south side of the Thames, witnesses said. 

Witnesses said the attackers stabbed people in the street and in pubs and restaurants in Borough Market. 

- Police said armed police had responded to the reports of stabbings in Borough Market and shots had been fired. 

"Armed response officers then responded very quickly and bravely and confronted the three male suspects who were shot and killed on Borough Market," Mark Rowley, Britain's top anti-terrorism officer, said. 

"The suspects had been confronted and shot by police within eight minutes of the first call. The suspects were wearing what looked like explosive vests but these were later established to be hoaxes," he said. 

The men were wearing what appeared to be canisters attached to their bodies. One of them was shown in a photograph lying on the ground outside the Wheatsheaf pub. 

Another man, was also reported to be an attacker, was pictured on the ground a short distance away. Witnesses said they heard gunfire in the area. 

The police said the vests were later established to be hoaxes. A Reuters reporter nearby said he heard loud bangs afterwards that may have been controlled explosions. 

- Terror attack? At 12:25 A.M. British time on Sunday the incidents at London Bridge and Borough Market were declared as terrorist incidents. 

"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," Prime Minister Theresa May said just over four days before voting is due to begin in a June 8 national election. 

"This is a fast moving investigation," May said. "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." 

London's Metropolitan Police Counter Terrorism Command is leading the investigation. 

- Who? It was not clear who might be responsible for the attack. 

Islamic State earlier on Saturday sent out a call on instant messaging service Telegram urging its followers to launch attacks with trucks, knives and guns against "Crusaders" during the Muslim holy month of Ramadan. 

- The attack came less than two weeks after a suicide bomber Salman Abedi blew himself up at a concert in Manchester on May 22, killing at least 22. 

Britain raised its terror threat to the highest level of "critical" and deployed troops on the streets on May 23, a day after the Manchester suicide attack. The critical level means another attack could be imminent. It was reduced to "severe", which means an attack is highly likely, on May 27. 

On March 22, Khalid Masood ploughed a rented car into pedestrians and stabbed a policeman to death before being shot dead. Five were killed by the attacker. 

- The United Kingdom is due to hold a national election on June 8.
