Trump responds to UK attack with apparent criticism of London Mayor Sadiq Khan

LONDON, June 4 (Reuters) - U.S. President Donald Trump tweeted on Sunday about a militant attack in London which killed seven people, quoting London Mayor Sadiq Khan telling Britons not to be alarmed, in what appeared to be a criticism of Khan's response to the incident.

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

At this time 21 of the 48 injured are in critical condition.

Earlier Khan had said Britons should not be alarmed to see a higher police presence on the streets of London following the incident.
