Royal Air Force Typhoon FGR4s have joined forces with France's air force in a coordinated attack targeting an subterranean weapons facility in Syria used by the IS group, as stated by the UK Ministry of Defence.
The site, identified by surveillance, was assessed as housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a number of entry passages down to the site... preliminary assessments indicate the strike was effective," officials stated.
There was no evidence of any civilian impact in the strike on Saturday evening and all the aircraft returned safely, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - enforced militant control over large swathes of Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and commitment to stand shoulder to shoulder with allied nations, to eliminate any revival of IS and their harmful and extremist ideologies in the region," the British Defence Secretary John Healey stated.
RAF aircraft have carried out patrols over Syrian airspace to "forestall any attempted resurgence" of IS subsequent to its routing at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of British forces who took part in this strike for their skill and their bravery," the Defence Secretary added. "They were among thousands of British personnel deployed over Christmas and New Year. This mission, to take out militants who pose a risk to our safety, highlights how British military are ready to step up, throughout the year, keeping Britain secure within its borders and strong abroad."
During December, the American forces conducted what it termed a "large-scale strike" against Islamic State objectives in Syria, following an assault killed two US troops and a civilian interpreter in the Palmyra area.
The United Nations says IS still maintains roughly 5-7 thousand militants in both countries.
