British Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation on an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), according to the British defence ministry.
The facility, pinpointed through surveillance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountains just above the ancient city of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to strike a number of access tunnels providing entry to the site... early reports suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the strike late on Saturday and every plane involved returned to base without incident, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - alternatively referred to as ISIS - enforced jihadist rule over parts of both Syria and Iraq until 2019.
"This strike shows the UK's leading role, and commitment to operate in unison with our allies, to eradicate any resurgence of the terrorist group and their harmful and extremist ideologies in the area," Britain's Defence Chief the minister remarked.
British military aircraft have performed overwatch operations over Syrian airspace to "prevent any attempted resurgence" of the group subsequent to its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I extend gratitude to every member of the UK armed forces participating in this strike for their expertise and their valour," Healey said. "They were part of thousands of British personnel stationed over the festive period. This operation, to eliminate militants who endanger our safety, demonstrates how British military are prepared to act, continuously, protecting the UK within its borders and powerful internationally."
During December, the United States armed forces executed what it termed a "major assault" on Daesh sites in Syria, after an ambush killed two US troops and a civilian linguist in the Palmyra area.
The U.N. says Islamic State still has roughly 5-7 thousand combatants in Syria and Iraq.
