Royal Air Force Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack targeting an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, according to the UK Ministry of Defence.
The facility, pinpointed through intelligence, was believed to be containing munitions and bombs, the announcement noted, and was situated in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"The RAF jets used precision-guided Paveway IV munitions to target a number of access tunnels down to the depot... initial indications suggest the strike was effective," officials stated.
There was no indication of any civilian impact in the operation late on Saturday and each participating jet returned to base without incident, the MoD added.
The British jets were backed up by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as Daesh - imposed extremist governance over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike shows our UK leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any re-emergence of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary John Healey remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted resurgence" of the group after its routing at the climactic battle in Baghuz in the year 2019, the ministry said.
"I want to thank all the members of our armed forces who took part in this operation for their expertise and their courage," he commented. "They were part of a great many UK service members on duty over Christmas and New Year. This operation, to eliminate dangerous terrorists who threaten our security, demonstrates how our armed forces are always on standby, continuously, protecting the UK domestically and strong abroad."
Last December, the United States armed forces conducted what it described as a "major assault" against IS targets in Syria, after an assault claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The U.N. says Islamic State still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
