London Bridge terror incident: What we know

Here's what we know about police responding to two terrorism incidents in London late Saturday night.

Shortly before 1 a.m. in London, police declared terrorists responsible for the London Bridge and Borough Market incidents, which they said appear to be connected. Police say their investigation is continuing.

Six victims and three attackers were killed, according to Mark Rowley, head of counter-terrorism for Metropolitan Police. London Ambulance Service said they had taken at least 30 patients to six hospitals, and treated a number of people at the scene with less serious injuries.

London Bridge

British police responded to eyewitness reports late Saturday that a van plowed into pedestrians on London Bridge.

On London Bridge, witnesses described seeing a white van mounting the sidewalk and injuring at least six people at about 10:30 p.m. A BBC reporter who was on the bridge at the time said the van was driving around 50 mph.

London Bridge, which crosses the River Thames in London, was closed in both directions.

Borough Market 

After the London Bridge incident, police say, the van continued on to Borough Market, an area of the capital known for its pubs, food stalls and lively nightlife. Police say the suspects exited the van and stabbed pedestrians and an off-duty British Transport Police officer.

Responding officers shot and killed three male suspects, police say.

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.
