RAF Typhoon fighter aircraft have joined forces with French warplanes in a joint strike against an hidden munitions depot in Syria used by the IS group, as stated by the British defence ministry.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the announcement noted, and was positioned in mountains just above the historic site of Palmyra in central Syria.
"The RAF jets utilized laser-guided Paveway IV weapons to target a several approach shafts down to the site... early reports suggest the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the strike on Saturday evening and all the aircraft returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - imposed extremist governance over large swathes of both Syria and Iraq until 2019.
"This strike demonstrates the UK's leading role, and resolve to work closely with allied nations, to eradicate any revival of the terrorist group and their harmful and extremist ideologies in the region," UK Defence Secretary John Healey remarked.
UK warplanes have conducted overwatch operations over Syria to "deter any efforts to regroup" of IS following its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to all the members of British forces participating in this operation for their professionalism and their bravery," he added. "They were among numerous British troops deployed over the festive period. This mission, to eliminate terrorist threats who threaten our way of life, demonstrates how UK forces are ready to step up, throughout the year, ensuring Britain's security within its borders and powerful internationally."
Last December, the United States armed forces executed what it described as a "large-scale strike" on Islamic State objectives in the country, after an assault killed two US troops and a civilian linguist in the Palmyra area.
The U.N. says IS still has between 5,000 and 7,000 combatants in both countries.
