LONDON (Reuters) - U.S. President Donald Trump on Tuesday said that terrorists should be treated with “toughness and strength” after a man drove a car into members of the public and a security barrier outside Britain’s parliament, injuring three.

“Another terrorist attack in London...These animals are crazy and must be dealt with through toughness and strength!” Trump tweeted.

British police arrested a man on suspicion of terrorism offences, saying he appeared to deliberately drive into cyclists before ramming a car into security barriers outside the British parliament in London.
