Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a coordinated attack on an hidden munitions depot in Syria used by the Daesh militant organization, as stated by the British defence ministry.
The site, located using intelligence, was thought to be storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our aircraft employed Paveway IV guided bombs to strike a series of entry passages leading to the site... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike late on Saturday and every plane involved returned to base without incident, the MoD added.
The British jets were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as Daesh - established militant control over parts of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and resolve to work closely with our allies, to stamp out any revival of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the minister said.
RAF aircraft have carried out patrols over Syria to "prevent any efforts to regroup" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank every member of the UK armed forces involved in this operation for their professionalism and their bravery," the Defence Secretary said. "They were part of numerous British troops deployed over the holidays. This action, to remove dangerous terrorists who endanger our safety, highlights how our armed forces are ready to step up, throughout the year, ensuring Britain's security domestically and powerful internationally."
In December, the American forces executed what it termed a "massive strike" on IS targets in Syria, after an ambush killed two US servicemembers and a civilian linguist in Palmyra.
The UN says IS still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
