RAF Typhoon FGR4s have conducted a mission with France's air force in a combined operation against an subterranean weapons facility in Syrian territory used by the Daesh militant organization, according to the British defence ministry.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the statement said, and was located in mountains just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes employed precision-guided Paveway IV munitions to target a several access tunnels leading to the depot... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian casualties in the attack late on Saturday and each participating jet returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - enforced extremist governance over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates British leadership, and determination to stand shoulder to shoulder with our allies, to eradicate any resurgence of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary said.
UK warplanes have performed patrols over Syria to "prevent any attempted comeback" of IS subsequent to its defeat at the battle of Baghuz in 2019, the authorities noted.
"I want to thank the personnel of the UK armed forces who took part in this mission for their skill and their bravery," the Defence Secretary commented. "Including them were thousands of UK service members stationed over Christmas and New Year. This mission, to remove terrorist threats who pose a risk to our way of life, shows how British military are prepared to act, throughout the year, protecting the UK domestically and strong abroad."
In December, the United States armed forces executed what it called a "major assault" against Islamic State objectives in the country, after an attack killed two US troops and a civilian linguist in Palmyra.
The U.N. reports IS still has between 5,000 and 7,000 militants in Syria and Iraq.
