RAF Typhoon FGR4s have operated alongside French aircraft in a combined operation targeting an underground arms cache in Syrian territory employed by the Daesh militant organization, according to the UK Ministry of Defence.
The site, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was situated in mountainous terrain just north of the historic site of Palmyra in Syria's central region.
"Our fighter planes employed Paveway IV guided bombs to strike a number of access tunnels down to the depot... initial indications suggest the target was engaged successfully," the MoD said.
There was no indication of any harm to civilians in the strike late on Saturday and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as the so-called Islamic State - established extremist governance over parts of Iraq and Syria until 2019.
"This action underscores our UK leadership, and determination to work closely with our partners, to stamp out any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the Defence Secretary said.
UK warplanes have conducted surveillance missions over Syria to "prevent any attempted resurgence" of Islamic State following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of British forces participating in this mission for their professionalism and their bravery," Healey said. "They were among numerous British troops deployed over the festive period. This operation, to eliminate terrorist threats who pose a risk to our security, shows how UK forces are prepared to act, throughout the year, keeping Britain secure domestically and strong abroad."
