British Air Force Typhoon FGR4s have conducted a mission with France's air force in a combined operation on an underground arms cache in Syrian territory employed by the Islamic State group (IS), per a report from the British defence ministry.
The site, identified by intelligence, was believed to be storing arms and explosives, the release indicated, and was located in mountains just above the ancient city of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to hit a series of entry passages leading to the depot... initial indications are that the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the strike on Saturday evening and every plane involved returned safely, the ministry further stated.
The British jets were supported by a Voyager tanker plane.
Daesh - referred to as the so-called Islamic State - imposed jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and resolve to work closely with our partners, to eliminate any re-emergence of IS and their violent and radical beliefs in the region," the British Defence Secretary the minister remarked.
UK warplanes have performed surveillance missions over Syrian airspace to "prevent any attempted resurgence" of the group subsequent to its routing at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank the personnel of our armed forces participating in this mission for their expertise and their courage," he added. "Including them were numerous UK service members deployed over Christmas and New Year. This mission, to eliminate dangerous terrorists who pose a risk to our security, highlights how UK forces are ready to step up, throughout the year, ensuring Britain's security within its borders and strong abroad."
Last December, the United States armed forces executed what it described as a "major assault" targeting Daesh sites in the country, following an attack claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The U.N. reports IS still boasts an estimated 5,000 to 7,000 combatants in Syria and Iraq.
