Five people have been killed in a "sick and depraved" terror attack that brought carnage to the heart of London, including the police officer who was stabbed and his assailant.

Mark Rowley, Scotland Yard's top anti-terror officer, confirmed that 40 people were injured after the attacker - armed with two large knives - mowed down pedestrians with his car on Westminster Bridge then rushed at the gates in front of the Houses of Parliament, stabbing a plain-clothes policeman before he was shot by armed officers on Wednesday afternoon.

Here's how the world's media reacted.
