RAF Typhoon fighter aircraft have operated alongside French aircraft in a joint strike on an underground arms cache in Syria operated by the Islamic State group (IS), as stated by the UK's MoD.
The site, pinpointed through surveillance, was assessed as storing arms and explosives, the release indicated, and was situated in mountainous terrain just above the ancient city of Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to strike a number of entry passages providing entry to the depot... early reports are that the objective was successfully hit," the ministry announced.
There was no evidence of any civilian impact in the attack conducted Saturday night and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - imposed militant control over large swathes of both Syria and Iraq until 2019.
"This action underscores our UK leadership, and resolve to stand shoulder to shoulder with allied nations, to eradicate any revival of IS and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief John Healey stated.
UK warplanes have carried out overwatch operations over Syria to "prevent any attempted resurgence" of Islamic State subsequent to its routing at the climactic battle in Baghuz in the year 2019, the ministry said.
"I extend gratitude to every member of the UK armed forces participating in this operation for their skill and their valour," he said. "They were part of a great many UK service members on duty over the holidays. This mission, to take out terrorist threats who endanger our safety, shows how UK forces are prepared to act, continuously, protecting the UK domestically and influential overseas."
During December, the American forces carried out what it described as a "major assault" on Daesh sites in the country, after an assault killed two American soldiers and a local interpreter in Palmyra.
The United Nations reports IS still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
