Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a coordinated attack targeting an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, according to the British defence ministry.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the release indicated, and was situated in mountains just north of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to target a series of approach shafts down to the facility... preliminary assessments suggest the strike was effective," the MoD said.
There was no sign of any civilian impact in the operation conducted Saturday night and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
IS - also known as Daesh - imposed extremist governance over parts of both Syria and Iraq until 2019.
"This strike demonstrates our UK leadership, and resolve to work closely with allied nations, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the area," Britain's Defence Chief the Defence Secretary said.
British military aircraft have carried out surveillance missions over Syrian airspace to "forestall any attempted comeback" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank every member of our armed forces involved in this operation for their professionalism and their bravery," he commented. "Including them were numerous British troops deployed over Christmas and New Year. This operation, to eliminate terrorist threats who endanger our security, demonstrates how our armed forces are prepared to act, throughout the year, ensuring Britain's security domestically and influential overseas."
During December, the US military carried out what it called a "massive strike" on IS targets in the country, after an ambush claimed the lives of two American soldiers and a local interpreter in the Palmyra area.
The United Nations says Daesh still boasts roughly 5-7 thousand militants in Syria and Iraq.
