British PM Vows Change

British Prime Minister Theresa May has vowed that “things need to change” following the car-and-knife rampage in the heart of the British capital late Saturday. A short while later, police said 12 people had been arrested in Barking, East London, as officers continued to search a number of addresses in the area.

“We cannot and must not pretend that things can continue as they are,” she said in a strongly worded statement to reporters outside her official residence in London on Sunday. “There is — to be frank — far too much tolerance of extremism in our country.”

Seven people died and nearly 50 were injured when a van barreled into pedestrians on London Bridge, and then three attackers embarked on a stabbing spree at nearby Borough Market. It was the third terrorist attack on British soil within as many months. No details have been released about the casualties, but a Canadian citizen was among those killed, the country’s Prime Minister Justin Trudeau said in a statement on Sunday.

“We grieve with the families and friends of those who have lost loved ones, and wish all those injured a speedy and full recovery,” he said in the statement.

The National Health Service in England told NBC News that 21 people injured in the attack were in critical condition.
