RAF Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack on an hidden munitions depot in Syrian territory used by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, located using surveillance, was believed to be storing arms and explosives, the announcement noted, and was positioned in mountains just north of the historic site of Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to strike a series of entry passages leading to the facility... preliminary assessments are that the target was engaged successfully," officials stated.
There was no evidence of any civilian impact in the operation late on Saturday and each participating jet returned to base without incident, the MoD added.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - imposed extremist governance over large swathes of Syria and Iraq until 2019.
"This action underscores British leadership, and commitment to work closely with our allies, to eliminate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary John Healey stated.
British military aircraft have carried out surveillance missions over Syrian airspace to "deter any efforts to regroup" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank all the members of the UK armed forces involved in this operation for their professionalism and their valour," the Defence Secretary commented. "They were part of a great many British troops deployed over the festive period. This operation, to remove terrorist threats who endanger our safety, highlights how UK forces are ready to step up, throughout the year, keeping Britain secure within its borders and influential overseas."
During December, the US military conducted what it called a "massive strike" on Islamic State objectives in the country, after an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations says Islamic State still maintains an estimated 5,000 to 7,000 combatants in Syria and Iraq.
