British Air Force Typhoon fighter aircraft have joined forces with French warplanes in a coordinated attack against an underground arms cache in Syrian territory employed by the IS group, as stated by the UK's MoD.
The site, located using surveillance, was believed to be housing weapons and explosive materials, the announcement noted, and was situated in mountains just north of the historic site of Palmyra in central Syria.
"The RAF jets employed laser-guided Paveway IV weapons to target a series of access tunnels down to the facility... initial indications suggest the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the attack conducted Saturday night and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - imposed extremist governance over significant areas in Iraq and Syria prior to its 2019 collapse.
"This strike shows British leadership, and commitment to operate in unison with our allies, to stamp out any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary stated.
British military aircraft have performed surveillance missions over Syria to "deter any attempted comeback" of IS subsequent to its defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I extend gratitude to all the members of British forces participating in this operation for their professionalism and their valour," he said. "Including them were thousands of British personnel deployed over the festive period. This mission, to remove militants who pose a risk to our safety, demonstrates how our armed forces are prepared to act, throughout the year, keeping Britain secure at home and influential overseas."
During December, the American forces executed what it described as a "massive strike" against Daesh sites in the country, after an attack resulted in the deaths of two US troops and a local interpreter in Palmyra.
The United Nations reports IS still boasts roughly 5-7 thousand fighters in Syria and Iraq.
