British Air Force Typhoon jets have joined forces with French warplanes in a coordinated attack targeting an hidden munitions depot in Syria operated by the Daesh militant organization, as stated by the UK's MoD.
The site, identified by surveillance, was thought to be containing munitions and bombs, the announcement noted, and was situated in mountains just to the north of the ancient city of Palmyra in central Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to hit a series of entry passages down to the site... initial indications indicate the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the strike conducted Saturday night and every plane involved made a safe return, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - imposed extremist governance over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation shows British leadership, and resolve to stand shoulder to shoulder with allied nations, to eradicate any re-emergence of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief John Healey said.
British military aircraft have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of Islamic State following its military defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank all the members of the UK armed forces involved in this operation for their expertise and their valour," he added. "They were among thousands of British troops on duty over Christmas and New Year. This action, to take out militants who endanger our safety, demonstrates how British military are ready to step up, continuously, keeping Britain secure within its borders and powerful internationally."
Last December, the US military carried out what it termed a "large-scale strike" targeting Daesh sites in Syria, after an ambush claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The U.N. says IS still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
