British Air Force Typhoon FGR4s have joined forces with French warplanes in a combined operation on an subterranean weapons facility in Syrian territory used by the IS group, as stated by the British defence ministry.
The facility, pinpointed through intelligence, was believed to be storing arms and explosives, the release indicated, and was located in mountains just north of the ancient city of Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to strike a number of access tunnels leading to the facility... early reports suggest the strike was effective," the MoD said.
There was no indication of any civilian casualties in the operation on Saturday evening and each participating jet returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as the so-called Islamic State - enforced extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores the UK's leading role, and resolve to stand shoulder to shoulder with our allies, to eradicate any resurgence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary stated.
British military aircraft have conducted patrols over Syria to "forestall any efforts to regroup" of Islamic State after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of British forces participating in this operation for their professionalism and their courage," Healey commented. "They were among thousands of British troops stationed over the festive period. This action, to eliminate dangerous terrorists who threaten our security, demonstrates how our armed forces are ready to step up, continuously, ensuring Britain's security within its borders and strong abroad."
Last December, the American forces conducted what it termed a "major assault" targeting Daesh sites in the country, subsequent to an attack claimed the lives of two US troops and a local interpreter in Palmyra.
The UN reports IS still maintains between 5,000 and 7,000 combatants in both countries.
