British Air Force Typhoon jets have joined forces with French aircraft in a coordinated attack on an underground arms cache in Syria operated by the IS group, as stated by the British defence ministry.
The facility, located using intelligence, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountains just north of Palmyra in Syria's central region.
"The RAF jets utilized Paveway IV guided bombs to target a series of access tunnels down to the depot... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the operation late on Saturday and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - alternatively referred to as the so-called Islamic State - established jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates British leadership, and commitment to work closely with our allies, to eliminate any revival of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "deter any attempted resurgence" of the group subsequent to its defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces involved in this strike for their professionalism and their bravery," Healey said. "Including them were numerous UK service members on duty over the festive period. This action, to take out terrorist threats who endanger our security, demonstrates how UK forces are ready to step up, throughout the year, keeping Britain secure within its borders and influential overseas."
In December, the US military carried out what it described as a "massive strike" against Islamic State objectives in Syria, after an assault killed two US servicemembers and a local interpreter in Palmyra.
The UN reports Islamic State still boasts between 5,000 and 7,000 militants in both countries.
