British Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation against an underground arms cache in Syrian territory operated by the Daesh militant organization, per a report from the UK's MoD.
The facility, pinpointed through intelligence, was believed to be storing arms and explosives, the statement said, and was situated in mountains just north of Palmyra in Syria's central region.
"The RAF jets utilized laser-guided Paveway IV weapons to target a several approach shafts providing entry to the facility... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no indication of any harm to civilians in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - imposed jihadist rule over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This strike underscores the UK's leading role, and commitment to work closely with our allies, to stamp out any resurgence of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary the Defence Secretary said.
UK warplanes have conducted surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State after its routing at the battle of Baghuz in 2019, the ministry said.
"I want to thank all the members of British forces involved in this strike for their skill and their bravery," the Defence Secretary added. "Including them were thousands of UK service members on duty over the holidays. This mission, to eliminate terrorist threats who threaten our way of life, highlights how British military are prepared to act, all year round, ensuring Britain's security within its borders and influential overseas."
During December, the United States armed forces carried out what it described as a "major assault" against Islamic State objectives in Syria, subsequent to an assault killed two US troops and a civilian interpreter in Palmyra.
The United Nations reports IS still has between 5,000 and 7,000 fighters in Iraq and Syria.
