LONDON, June 4 (Xinhua) -- Six people have died in addition to the three attackers shot dead by police in the London Bridge and Borough Market attack Saturday night, Met's Counter Terrorism Command said.
Assistant Commissioner Mark Rowley of Metropolitan Police said since late Saturday, the Metropolitan Police Service has been responding to incidents in the London Bridge and Borough Market areas of south London.
Attackers drove a van at high speed into pedestrians on London Bridge just after 10 p.m. on Saturday before continuing to drive from the bridge to Borough Market.
There, they jumped out of the van and stabbed people, including a British Transport Police officer who has serious but not life-threatening injuries to his face, head and leg, Sky news reported.
Within eight minutes, armed police confronted three male attackers, shooting them dead in Borough Market.
"We are treating this as a terrorist incident and a full investigation is already underway, led by the Met's Counter Terrorism Command," said Rowley.
"At this stage, we believe that six people have died in addition to the three attackers shot dead by police. And at least 20 casualties have been taken to six hospitals across London," he said.
"We believe three people were involved but we still have some more inquiries to be 100 percent confident of that," Rowley said.
Prime Minister Theresa May has returned to Downing Street for security briefings and will chair a meeting of the Government's emergency response committee later Sunday.
She said the "terrible incident" was being treated as a "potential act of terrorism."
