US President Donald Trump on Sunday tweeted about the weekend terror attack in London.

"We must stop being politically correct and get down to the business of security for our people," Trump tweeted. "If we don't get smart it will only get worse."

"At least 7 dead and 48 wounded in terror attack and Mayor of London says there is 'no reason to be alarmed!'"

British Interior Minister Amber Rudd on Sunday said that the attack's perpetrators were probably "radical Islamist terrorists."

Three terrorists wearing what seemed to be explosive belts rammed passersby on the London Bridge before exiting their vehicle and going on a stabbing spree at the nearby Borough Market.

After approximately eight minutes, London police shot the terrorists and killed them.

48 people were injured in the attack, some of them critically.
