RAF Typhoon jets have joined forces with French warplanes in a joint strike on an hidden munitions depot in Syria employed by the IS group, as stated by the UK's MoD.
The facility, identified by intelligence, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in mountainous terrain just north of Palmyra in Syria's central region.
"Our fighter planes used laser-guided Paveway IV weapons to hit a number of entry passages leading to the depot... early reports suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - established militant control over parts of Iraq and Syria until 2019.
"This operation underscores British leadership, and determination to stand shoulder to shoulder with our allies, to eradicate any revival of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary stated.
RAF aircraft have conducted patrols over Syria to "deter any attempted resurgence" of Islamic State subsequent to its routing at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces who took part in this mission for their expertise and their bravery," the Defence Secretary commented. "They were part of a great many UK service members on duty over Christmas and New Year. This operation, to remove militants who threaten our safety, highlights how UK forces are ready to step up, continuously, ensuring Britain's security at home and powerful internationally."
Last December, the American forces executed what it termed a "major assault" targeting Islamic State objectives in Syria, subsequent to an ambush killed two US troops and a civilian linguist in Palmyra.
The U.N. says Daesh still boasts roughly 5-7 thousand fighters in both countries.
