RAF Typhoon FGR4s have conducted a mission with French warplanes in a coordinated attack on an subterranean weapons facility in Syria used by the IS group, per a report from the UK's MoD.
The location, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just above the ancient city of Palmyra in central Syria.
"Our aircraft utilized Paveway IV guided bombs to target a several entry passages down to the site... early reports suggest the strike was effective," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as Daesh - established jihadist rule over parts of both Syria and Iraq until 2019.
"This operation shows British leadership, and resolve to operate in unison with our partners, to stamp out any revival of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the Defence Secretary stated.
British military aircraft have performed overwatch operations over Syria to "forestall any attempted comeback" of Islamic State subsequent to its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank the personnel of the UK armed forces participating in this strike for their professionalism and their courage," he commented. "Including them were numerous British troops stationed over Christmas and New Year. This operation, to eliminate dangerous terrorists who threaten our safety, demonstrates how UK forces are prepared to act, throughout the year, keeping Britain secure within its borders and influential overseas."
During December, the United States armed forces carried out what it called a "massive strike" against IS targets in Syria, following an attack claimed the lives of two US troops and a civilian interpreter in Palmyra.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 fighters in both countries.
