Donald Trump has posted footage of the man being fatally attacked by a tiger at a UK wildlife park to 13 million followers on his Truth Social platform.

The US president accompanied the short clip with the signed message: “Don’t ever mess with nature!”

Mr Trump followed this up a short time later with a separate post featuring a video montage that appeared to show a series of other people being mauled by lions accompanied by an upbeat soundtrack.

A health and safety investigation has been launched into the incident at Yorkshire Wildlife Park in Doncaster, where a man named in reports as William Chapman was killed after entering the tiger enclosure on Saturday.

The park will remain closed on Wednesday for a fifth day following the attack.

Emergency services were contacted shortly after 1.30pm on October 10 when Mr Chapman, who police said was visiting the park alone, entered the enclosure.

He was pronounced dead at the scene.
