A man set himself on fire in the early hours of Tuesday outside Kensington Palace, the central London home of Prince William and his wife Kate, and later died of his injuries, British police said.

Two fire extinguishers could be seen next to a police tent set up at the scene of the incident near the large windows of the palace’s Orangery.

Two people in white forensic suits put a green petrol canister in a transparent evidence bag under a tree nearby, an AFP photographer saw.

There was a strong smell of petrol at the scene, which was cordoned off to tourists.

“This incident is not being treated as terrorist-related,” the police said in a statement.

Officers were called to an area near the locked parks of the palace at 3:06am (0306 GMT) “following reports of a man behaving suspiciously” the police said in a statement.

“Officers attended and found a man, believed to be aged in his forties, ablaze,” the statement said.

The man could not be saved and was declared dead half an hour after emergency services arrived on site.
