RAF Typhoon FGR4s have conducted a mission with French aircraft in a combined operation against an hidden munitions depot in Syrian territory employed by the IS group, per a report from the British defence ministry.
The facility, located using intelligence, was believed to be storing arms and explosives, the statement said, and was positioned in mountains just to the north of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to target a number of access tunnels down to the site... preliminary assessments indicate the target was engaged successfully," officials stated.
There was no indication of any harm to civilians in the strike conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The British jets were backed up 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 Syria and Iraq prior to its 2019 collapse.
"This operation underscores our UK leadership, and resolve to stand shoulder to shoulder with our allies, to eradicate any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary stated.
British military aircraft have carried out surveillance missions over Syrian airspace to "forestall any attempted comeback" of IS after its military defeat at the battle of Baghuz in 2019, the authorities noted.
"I must thank every member of our armed forces who took part in this strike for their professionalism and their bravery," the Defence Secretary added. "Including them were numerous UK service members deployed over the festive period. This operation, to eliminate terrorist threats who threaten our way of life, highlights how British military are prepared to act, continuously, ensuring Britain's security domestically and powerful internationally."
Last December, the American forces carried out what it called a "major assault" against Islamic State objectives in Syria, following an assault resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The U.N. estimates Islamic State still has between 5,000 and 7,000 combatants in both countries.
