Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike on an hidden munitions depot in Syrian territory operated by the Islamic State group (IS), per a report from the UK's MoD.
The site, identified by surveillance, was thought to be storing arms and explosives, the statement said, and was situated in mountains just to the north of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to strike a number of entry passages leading to the site... early reports suggest the strike was effective," the ministry announced.
There was no indication of any civilian impact in the strike late on Saturday and every plane involved returned safely, the MoD added.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as ISIS - enforced extremist governance over parts of Syria and Iraq until 2019.
"This action underscores British leadership, and determination to stand shoulder to shoulder with our allies, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the area," UK Defence Secretary the Defence Secretary said.
UK warplanes have performed surveillance missions over Syrian airspace to "prevent any attempted resurgence" of Islamic State subsequent to its military defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I must thank the personnel of the UK armed forces participating in this operation for their professionalism and their valour," Healey commented. "They were part of a great many British personnel on duty over the festive period. This operation, to eliminate militants who endanger our safety, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security within its borders and strong abroad."
During December, the US military carried out what it termed a "major assault" against IS targets in Syria, after an attack resulted in the deaths of two US troops and a local interpreter in Palmyra.
The U.N. reports IS still boasts an estimated 5,000 to 7,000 combatants in Iraq and Syria.
