Donald Trump has hit back at Sadiq Khan on Twitter after the mayor of London made comments about the US president playing golf during Hurricane Dorian.
Intially misspelling Mr Khan's first and last names before reposting the tweets, Mr Trump said: "The incompetent Mayor of London, Sadique Kahn, was bothered that I played a very fast round of golf yesterday. Many Pols exercise for hours, or travel for weeks. Me, I run through one of my courses (very inexpensive). President Obama would fly to Hawaii.
"Kahn should focus on 'knife crime,' which is totally out of control in London. People are afraid to even walk the streets. He is a terrible mayor who should stay out of our business!"
President Trump posted the tweets in response to comments made by Mr Khan in an interview with the American magazine, Politico, after Mr Trump pulled out of a trip to Poland for an event marking the 80th anniversary of the invasion of Poland. US Vice President Mike Pence was sent in his place.
The US president is said to have spent Monday playing golf at his Trump National Golf Club, which is in Virginia, instead, while Hurricane Dorian swept the Bahamas and looms ready to batter the east coast.
Mr Khan told the publication, 'he's clearly busy dealing with a hurricane out on the golf course'.
The exchange is the latest in a series of rows between the pair, with the president describing Mr Khan as "a stone cold loser" shortly before his state visit to the UK in June.
