British Air Force Typhoon jets have joined forces with France's air force in a combined operation on an hidden munitions depot in Syria operated by the IS group, according to the British defence ministry.
The facility, located using reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountains just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a several entry passages leading to the facility... initial indications indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - imposed extremist governance over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores our UK leadership, and commitment to operate in unison with our allies, to eliminate any resurgence of IS and their violent and radical beliefs in the region," the British Defence Secretary John Healey stated.
UK warplanes have conducted surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State subsequent to its routing at the battle of Baghuz in the year 2019, the authorities noted.
"I must thank the personnel of our armed forces involved in this operation for their professionalism and their bravery," he commented. "They were among thousands of British personnel on duty over the holidays. This operation, to eliminate militants who pose a risk to our safety, shows how our armed forces are always on standby, all year round, protecting the UK at home and powerful internationally."
In December, the US military conducted what it called a "major assault" against IS targets in Syria, after an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The U.N. says IS still maintains between 5,000 and 7,000 militants in Iraq and Syria.
