RAF Typhoon jets have operated alongside French warplanes in a combined operation against an hidden munitions depot in Syrian territory employed by the Daesh militant organization, according to the UK's MoD.
The facility, located using reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just north of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a several access tunnels leading to the site... early reports are that the target was engaged successfully," officials stated.
There was no evidence of any civilian casualties in the operation on Saturday evening and each participating jet returned safely, the MoD added.
The Typhoon fighters were backed up by a Voyager tanker plane.
IS - alternatively referred to as the so-called Islamic State - enforced jihadist rule over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike underscores our UK leadership, and commitment to work closely with our allies, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary stated.
British military aircraft have conducted overwatch operations over Syrian airspace to "prevent any efforts to regroup" of the group after its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank every member of the UK armed forces who took part in this mission for their expertise and their valour," he added. "They were among thousands of British troops deployed over the holidays. This mission, to eliminate militants who endanger our safety, highlights how British military are ready to step up, all year round, keeping Britain secure at home and powerful internationally."
Last December, the United States armed forces conducted what it called a "massive strike" on Islamic State objectives in Syria, after an ambush resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations says Islamic State still maintains roughly 5-7 thousand militants in Iraq and Syria.
