Officials are investigating the cause of a fire that started at the Trump International Hotel and Tower in New York.

The blaze started on the 47th floor of the building, which overlooks Central Park, in the early hours of Friday morning.

The fire brigade was called at around 4.30am local time (9.30am GMT) and the fire was extinguished at around 5.20am (10.20am GMT), local television reported .

The Fire Department of New York is investigating the cause of the blaze but have not found any indication it was "suspicious".

A protester attempted to set himself on fire outside one of Mr Trump's hotels in Washington in January.

“I was trying to light myself on fire as an act of protest,” the man said, before being taken for medical treatment. “ Protesting the fact that we've elected someone who is completely incapable of respecting the Constitution of the United States.”
