RAF Typhoon FGR4s have joined forces with French warplanes in a joint strike on 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 housing weapons and explosive materials, the statement said, and was situated in mountains just north of the ancient city of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to hit a number of approach shafts down to the depot... initial indications indicate the target was engaged successfully," officials stated.
There was no indication of any civilian casualties in the strike conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as Daesh - enforced extremist governance over parts of both Syria and Iraq until 2019.
"This strike underscores our UK leadership, and resolve to operate in unison with allied nations, to stamp out any revival of IS and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary said.
UK warplanes have conducted patrols over Syrian airspace to "deter any attempted comeback" of the group subsequent to its routing at the battle of Baghuz in 2019, the authorities noted.
"I must thank the personnel of British forces participating in this mission for their skill and their bravery," the Defence Secretary added. "Including them were numerous British troops deployed over Christmas and New Year. This action, to remove terrorist threats who pose a risk to our way of life, highlights how UK forces are ready to step up, all year round, ensuring Britain's security at home and powerful internationally."
Last December, the US military executed what it called a "massive strike" against IS targets in Syria, subsequent to an assault resulted in the deaths of two US troops and a civilian linguist in the Palmyra area.
The United Nations says Islamic State still maintains an estimated 5,000 to 7,000 combatants in both countries.
