British Air Force Typhoon FGR4s have conducted a mission with France's air force in a combined operation against an hidden munitions depot in Syria employed by the IS group, according to the UK's MoD.
The site, identified by reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was located in hills just above the historic site of Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a number of approach shafts leading to the facility... initial indications are that the objective was successfully hit," officials stated.
There was no sign of any civilian impact in the operation conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - imposed jihadist rule over parts of both Syria and Iraq before its territorial defeat in 2019.
"This strike shows our UK leadership, and determination to work closely with our allies, to eliminate any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the minister remarked.
British military aircraft have performed patrols over Syria to "deter any attempted resurgence" of Islamic State following its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of the UK armed forces participating in this operation for their expertise and their bravery," he commented. "They were part of a great many UK service members deployed over the holidays. This action, to eliminate dangerous terrorists who pose a risk to our safety, shows how our armed forces are prepared to act, all year round, ensuring Britain's security within its borders and powerful internationally."
In December, the American forces conducted what it called a "massive strike" targeting Islamic State objectives in the country, following an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The United Nations says Islamic State still boasts an estimated 5,000 to 7,000 fighters in both countries.
