Royal Air Force Typhoon FGR4s have joined forces with French warplanes in a combined operation against an subterranean weapons facility in Syrian territory operated by the IS group, as stated by the UK's MoD.
The site, identified by intelligence, was assessed as storing arms and explosives, the statement said, and was positioned in hills just above the ancient city of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to hit a several approach shafts providing entry to the site... preliminary assessments are that the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the attack on Saturday evening 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 the so-called Islamic State - enforced jihadist rule over significant areas in Iraq and Syria until 2019.
"This strike underscores British leadership, and resolve to work closely with our allies, to eradicate any revival of the terrorist group and their harmful and extremist ideologies in the area," the British Defence Secretary the Defence Secretary stated.
British military aircraft have carried out patrols over Syria to "deter any efforts to regroup" of the group subsequent to its defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I want to thank the personnel of our armed forces who took part in this mission for their skill and their courage," he said. "They were among numerous British troops deployed over the festive period. This mission, to remove militants who pose a risk to our safety, highlights how our armed forces are prepared to act, throughout the year, protecting the UK domestically and strong abroad."
Last December, the US military executed what it described as a "major assault" against IS targets in Syria, after an ambush resulted in the deaths of two US servicemembers and a civilian linguist in the Palmyra area.
The U.N. estimates IS still has an estimated 5,000 to 7,000 fighters in Iraq and Syria.
