British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a joint strike on an subterranean weapons facility in Syria used by the IS group, as stated by the UK's MoD.
The facility, identified by reconnaissance, was assessed as housing weapons and explosive materials, the release indicated, and was situated in hills just north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft used laser-guided Paveway IV weapons to hit a several entry passages providing entry to the depot... preliminary assessments are that the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the attack late on Saturday and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as Daesh - enforced extremist governance over parts of both Syria and Iraq until 2019.
"This operation demonstrates the UK's leading role, and resolve to stand shoulder to shoulder with our partners, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the area," the British Defence Secretary John Healey remarked.
British military aircraft have conducted overwatch operations over Syrian airspace to "prevent any attempted comeback" of IS subsequent to its routing at the Baghuz confrontation in 2019, the MoD reported.
"I must thank every member of our armed forces who took part in this mission for their expertise and their valour," the Defence Secretary added. "They were among thousands of British troops deployed over the holidays. This mission, to eliminate militants who threaten our way of life, highlights how UK forces are prepared to act, all year round, ensuring Britain's security at home and influential overseas."
In December, the United States armed forces executed what it called a "large-scale strike" on Islamic State objectives in the country, following an attack killed two US troops and a civilian interpreter in Palmyra.
The U.N. reports Islamic State still has between 5,000 and 7,000 militants in Syria and Iraq.
