British Air Force Typhoon jets have joined forces with France's air force in a joint strike on an subterranean weapons facility in Syrian territory used by the Daesh militant organization, as stated by the UK's MoD.
The facility, located using surveillance, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in hills just north of Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to strike a several entry passages leading to the facility... initial indications indicate the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the operation conducted Saturday night and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
The Islamic State group - referred to as the so-called Islamic State - established extremist governance over parts of Syria and Iraq until 2019.
"This strike shows British leadership, and commitment to stand shoulder to shoulder with allied nations, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary John Healey said.
UK warplanes have carried out surveillance missions over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its military defeat at the battle of Baghuz in the year 2019, the ministry said.
"I must thank all the members of the UK armed forces participating in this operation for their expertise and their courage," Healey said. "They were part of thousands of British personnel deployed over Christmas and New Year. This mission, to take out terrorist threats who threaten our safety, demonstrates how our armed forces are always on standby, continuously, protecting the UK within its borders and influential overseas."
In December, the United States armed forces executed what it described as a "large-scale strike" targeting IS targets in the country, subsequent to an attack resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The U.N. reports IS still boasts roughly 5-7 thousand fighters in both countries.
