I think Brexit was a good choice.BBC correspondent Tom Symonds outlines how events unfolded on Saturday night, saying witnesses described seeing a van crashing into pedestrians on the southern side of London Bridge.
Eyewitnesses said three people - armed with knives - were seen jumping out of the van and they began attacking.
Mr Symonds said a police shooting followed the attack but it was not clear who was shot, nor how many.
Some eyewitnesses claimed they saw one attacker dead or not moving, and another on the ground who may have been alive.
The alleged attackers ran round the corner from where the van hit the people on the bridge to Borough Market, he said.
Explosions were heard coming from the bridge, Mr Symonds says. He suspects it was a controlled explosion but nothing has been confirmed by police.
From being at the scene, Mr Symonds said he did not think the incident was continuing. Police are relaxed, there's a helicopter at the scene but it does look like it's over, he says.
