Prime Minister Theresa May said the incidents were being treated as "potential acts of terrorism."
Here is a quick look at the facts we know so far about Saturday night's terrorist attacks in London.
British police responded to reports that a van plowed into pedestrians on London Bridge at about 10:30 p.m. local time Saturday. Witnesses said a white van drove onto the sidewalk A BBC reporter who was on the bridge at the time said the van was driving around 50 mph.
The van continued on to Borough Market, an area of the capital known for its nightlife, where police say the suspects exited the vehicle and stabbed pedestrians.
There were also reports of a third stabbing, in the Vauxhall area of London, but police determined it was not connected to the terror incidents at London Bridge and Borough Market.
At least seven people died and 48 were injured in the van and stabbing attacks. The victims are being treated at five hospitals across London.
Several of the victims are said to be in critical condition.
Police said three suspects were fatally shot by authorities wihin eights minutes of first receiving the call.
"We believe there were 3 attackers and we believe they are dead," Metropolitan Police Commissioner Cressida Dick said Sunday.
All three suspects wore fake suicide-bomb vests, Prime Minister Theresa May said Sunday.
Was it terror?
Police have declared the attacks to be "terror incidents." May said it was being investigated as "a potential act of terrorism."
"We are all shocked and angry today but this is our city," said London Mayor Sadiq Khan in a statement Sunday. "We will never let these cowards win and we will never be cowed by terrorism."
No group has claimed responsibility for the attacks.
Will it impact U.K.'s upcoming election?
May announced that the general election will be held Thursday as scheduled. Candidates have suspended campaigning for the Sunday, but they will resume Monday.
What about the Ariana Grande benefit concert in Manchester?
Ariana Grande's One Love Manchester benefit concert for the victims of the bombing at the pop singer's show there last month will be held Sunday as scheduled. Grande's manager Scooter Braun said the "concert will not only continue, but will do so with greater purpose."
Police urged Londoners to be calm and vigilant and circulated a message that read: "Run," "Hide," "Tell."
"We are dealing with an incident on #LondonBridge, when we have more information we will update this twitter feed," they tweeted.
London Bridge was closed in both directions, British Transport Police said. Twitter users began uploading footage of police on the scene.
In the incident at Borough Market, an area that houses many food stalls and pubs and is popular with tourists, Metropolitan police said armed officers had been sent to the area after reports of stabbings, possibly at a restaurant.
The British Prime Minister's office said May is being regularly updated on the situation, and the White House said President Trump has been briefed.
"Whatever the United States can do to help out in London and the U. K., we will be there - WE ARE WITH YOU. GOD BLESS!" Trump tweeted.
Reports of the incident reflected fear that the incident could be terrorism. Britain has weathered two terrorism attacks in recent months. In March, four people were killed in London after Khalid Masood rammed his car into pedestrians on Westminster Bridge before fatally stabbing a policeman outside the Houses of Parliament.
On May 22, a British-born suicide bomber killed 22 people and injured 59 others at an Ariana Grande concert in Manchester, England.
