(CBSNEWS) – British police said two incidents, one on London Bridge and one at nearby Borough Market, are being treated as terrorist incidents.

Metropolitan Police Assistant Commissioner Mark Rowley gave an update on the incident, saying that the incident was a “protracted incident” that began on London Bridge and continued to Borough Market.

He said that six people died in the incident in addition to the three attackers shot dead by police. There were at least 20 causalities.

The three attackers were wearing what appeared to be explosive vests, but it was determined to be a hoax, Rowley said.

London Ambulance Services said more than 30 people were taken to five area hospitals.

A witness who was on the bridge told the BBC she saw a speeding van veer onto the pavement, striking as many as six people. Police then responded to reports of incidents at two more sites.

Armed police responded and shots were fired, police said. Police further said armed officers were responding to a third incident in the Vauxhall area.

The city transit authority Transport for London closed the bridge and ordered the London Bridge underground station evacuated.
