British Air Force Typhoon FGR4s have joined forces with French warplanes in a joint strike targeting an hidden munitions depot in Syria employed by the Daesh militant organization, per a report from the UK's MoD.
The facility, identified by intelligence, was believed to be storing arms and explosives, the statement said, and was situated in mountains just to the north of the ancient city of Palmyra in Syria's central region.
"The RAF jets used Paveway IV guided bombs to hit a number of approach shafts leading to the facility... preliminary assessments are that the strike was effective," the MoD said.
There was no indication of any civilian impact in the strike conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - enforced militant control over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This strike underscores British leadership, and resolve to work closely with allied nations, to eradicate any revival of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey said.
RAF aircraft have performed overwatch operations over Syria to "deter any attempted comeback" of the group after its defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to all the members of the UK armed forces who took part in this operation for their expertise and their courage," Healey added. "Including them were numerous UK service members deployed over Christmas and New Year. This action, to eliminate militants who threaten our security, demonstrates how our armed forces are ready to step up, throughout the year, protecting the UK within its borders and influential overseas."
Last December, the United States armed forces conducted what it described as a "large-scale strike" on Daesh sites in the country, subsequent to an ambush killed two US servicemembers and a local interpreter in the Palmyra area.
The United Nations reports IS still maintains between 5,000 and 7,000 combatants in both countries.
