"..Mark Rowley, head of counter-terrorism for Metropolitan Police, said police believe all of the attackers were killed, but investigations are underway to ensure there are no more.
Police said in a tweet that "the incidents at #LondonBridge & #BoroughMarket were declared as terrorist incidents" and appeared to be connected. It was not entirely clear if the police operation was over.
Earlier, Prime Minister Theresa May said the attacks were being investigated as a "potential act of terrorism.".."
There were also reports of a third incident, a stabbing in the Vauxhall area of London. That was subsequently said to be unrelated to the terror attack.
