Hotel staff in Turkey terrified British holidaymakers after staging a mock Islamic State-style attack for a poolside prank.
Sunbathers ran for their lives after workers carrying fake guns and a jerrycan marked fuel approached, The Sun newspaper reported.
One tourist claimed he had liquid from a container marked "fuel" poured over him and watched as his 'attacker' produced a lighter.
The incident at the five-star Grand Yazici Mares hotel in Icmeler was part of the hotel's entertainment programme and appears to have included characters such as Superman, alongside the 'terrorists'.
But coming less than two months after a gunmen killed 38 people at a resort in Tunisia, the prank has been viewed in bad taste.
A review on the TripAdvisor website recounting the event said that "one [staff member] was dressed in army pants walking round to pool with gun and pointing it at people".
Jason Phythian, 43, said "suddenly everyone became terrified" when men carrying "big guns" appeared on poolside.
“We were so relieved it was the hotel’s idea of entertainment for the day - they thought it was funny to run around the pool dressed as terrorists," he told The Sun.
Another tourist told the paper that a "crowd of British people" rushed to the hotel's management to complain.
“We were told it was just a joke and directed to take it up with our holiday rep," he said.
UK tour operator Jet2Holidays, which arranges package deals to the hotel, told ITV News that it had raised the issue with hotel management.
They have assured us it was never their intention to cause any offense or upset with their entertainment programme. This was a Hollywood themed poolside show, which included the characters Rambo and Superman, and it is always well received by the hotel's residents.
Many holiday makers are understood to have complained to the hotel management after the incident.
The hotel refused to comment to ITV News.
