British police are responding to an incident on the London Bridge amid reports of a vehicle slamming into pedestrians.
BBC reporter Holly Jones, who was on the bridge, said she saw a speeding van veer onto the pavement, striking as many as six people.
"We are dealing with an incident on #LondonBridge, when we have more information we will update this twitter feed," the Metropolitan Police Department tweeted late Saturday.
The city transit authority Transport for London has closed the bridge and ordered the London Bridge station evacuated.
One witness inside the station described the scene to Sky News.
"I was walking out of the London Bridge Station and there were police," Caroline Breniere said. "Some of them were coming by car, some of them were running. The traffic was stopped."
Will Haven, managing editor of the The Spectator in London, said on Twitter that there was a heavy police presence with at least 10 police vehicles and armed officers at the scene.
