RAF Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack targeting an subterranean weapons facility in Syrian territory employed by the IS group, as stated by the UK Ministry of Defence.
The facility, located using intelligence, was assessed as storing arms and explosives, the statement said, and was situated in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a series of approach shafts leading to the site... initial indications suggest the target was engaged successfully," officials stated.
There was no indication of any harm to civilians in the strike late on Saturday and every plane involved returned to base without incident, the MoD added.
The British jets were supported by a Voyager tanker plane.
IS - also known as the so-called Islamic State - enforced jihadist rule over parts of Syria and Iraq until 2019.
"This strike demonstrates the UK's leading role, and resolve to work closely with allied nations, to eradicate any resurgence of Daesh and their violent and radical beliefs in the area," the British Defence Secretary the minister said.
RAF aircraft have conducted surveillance missions over Syrian airspace to "forestall any efforts to regroup" of IS subsequent to its military defeat at the battle of Baghuz in 2019, the authorities noted.
"I extend gratitude to every member of our armed forces participating in this operation for their professionalism and their bravery," Healey commented. "They were part of thousands of British troops deployed over the festive period. This operation, to take out terrorist threats who threaten our way of life, demonstrates how British military are prepared to act, throughout the year, keeping Britain secure within its borders and influential overseas."
During December, the United States armed forces executed what it termed a "massive strike" on IS targets in the country, after an ambush resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The U.N. reports Islamic State still maintains an estimated 5,000 to 7,000 fighters in Syria and Iraq.
