British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack targeting an underground arms cache in Syria used by the IS group, per a report from the British defence ministry.
The location, located using surveillance, was assessed as housing weapons and explosive materials, the statement said, and was located in hills just to the north of Palmyra in Syria's central region.
"The RAF jets used Paveway IV guided bombs to hit a series of approach shafts providing entry to the depot... early reports indicate the target was engaged successfully," officials stated.
There was no evidence of any civilian impact in the operation on Saturday evening and every plane involved made a safe return, the ministry further stated.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as ISIS - established jihadist rule over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike underscores British leadership, and resolve to work closely with our allies, to stamp out any re-emergence of IS and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary stated.
RAF aircraft have carried out surveillance missions over Syrian airspace to "forestall any efforts to regroup" of Islamic State subsequent to its routing at the battle of Baghuz in 2019, the authorities noted.
"I want to thank every member of our armed forces participating in this operation for their professionalism and their bravery," he commented. "Including them were numerous UK service members deployed over the holidays. This operation, to remove militants who pose a risk to our safety, demonstrates how our armed forces are ready to step up, continuously, ensuring Britain's security at home and strong abroad."
In December, the United States armed forces carried out what it termed a "major assault" on Daesh sites in Syria, after an assault resulted in the deaths of two US troops and a local interpreter in Palmyra.
The UN reports IS still has an estimated 5,000 to 7,000 combatants in both countries.
