Mayor Khan urges public to stay calm and vigilant after knife attack

London Mayor Sadiq Khan said on Thursday the safety of Londoners was his top priority and the public should remain calm and vigilant after a knife attack in central London.

One woman was killed and five others injured by a man with suspected mental health issues who went on the rampage with a knife in central London late on Wednesday, an attack police said could be linked to terrorism.

"The safety of all Londoners is my number one priority," Khan said in a statement.

"I urge all Londoners to remain calm and vigilant. Please report anything suspicious to the police. We all have a vital role to play as eyes and ears for our police and security services and in helping to ensure London is protected."
