UPDATE | Trump and May speak after attacks in London

LONDON (AP) — The White House is condemning the attacks in London involving a car rampage and knife attack. President Donald Trump is said to be monitoring developments.

Spokesman Sean Spicer said today Trump spoke with British Prime Minister Theresa May and said the White House applauds "the quick response of British police and first responders" and condemns the attacks.

A vehicle mowed down pedestrians on a bridge and the attacker then stabbed a police officer outside the British Parliament. At least four people died, including the attacker and a police officer.

Spicer says that the city of London and the British government have the "full support" of the U.S. as they investigate the attack.

The U.S. Homeland Security Department says the security posture in the United States has not changed in the wake of the attack.
