Royal Air Force Typhoon jets have operated alongside French warplanes in a coordinated attack against an hidden munitions depot in Syria operated by the Daesh militant organization, per a report from the British defence ministry.
The facility, located using reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was situated in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes employed Paveway IV guided bombs to strike a several entry passages providing entry to the facility... early reports are that the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the strike conducted Saturday night and each participating jet made a safe return, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager refuelling tanker.
Daesh - referred to as the so-called Islamic State - enforced militant control over large swathes of Syria and Iraq until 2019.
"This action shows British leadership, and commitment to work closely with our partners, to eliminate any revival of IS and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary said.
RAF aircraft have carried out surveillance missions over Syria to "deter any attempted resurgence" of the group following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank every member of British forces participating in this operation for their skill and their courage," he added. "They were among numerous UK service members deployed over the festive period. This operation, to take out militants who endanger our way of life, highlights how British military are always on standby, all year round, ensuring Britain's security within its borders and influential overseas."
During December, the US military conducted what it termed a "massive strike" against Islamic State objectives in the country, after an assault killed two US troops and a civilian interpreter in the Palmyra area.
The UN reports Daesh still boasts between 5,000 and 7,000 fighters in both countries.
