British Air Force Typhoon fighter aircraft have operated alongside French aircraft in a joint strike against an subterranean weapons facility in Syria used by the IS group, per a report from the British defence ministry.
The facility, located using surveillance, was believed to be housing weapons and explosive materials, the statement said, and was situated in hills just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to strike a number of entry passages providing entry to the site... early reports indicate the objective was successfully hit," officials stated.
There was no indication of any civilian impact in the strike conducted Saturday night and every plane involved returned to base without incident, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
The Islamic State group - also known as ISIS - imposed militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike shows British leadership, and commitment to work closely with our allies, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief the minister remarked.
UK warplanes have performed surveillance missions over Syria to "forestall any efforts to regroup" of IS following its military defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I must thank every member of our armed forces involved in this operation for their professionalism and their valour," Healey commented. "Including them were numerous British troops deployed over the holidays. This mission, to eliminate militants who endanger our security, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security domestically and strong abroad."
In December, the American forces executed what it described as a "massive strike" targeting Islamic State objectives in Syria, after an attack killed two US servicemembers and a civilian interpreter in Palmyra.
The United Nations reports IS still boasts an estimated 5,000 to 7,000 combatants in both countries.
