Royal Air Force Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack on an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), as stated by the UK Ministry of Defence.
The site, identified by intelligence, was thought to be storing arms and explosives, the announcement noted, and was positioned in hills just north of the ancient city of Palmyra in Syria's central region.
"Our aircraft utilized Paveway IV guided bombs to target a number of entry passages leading to the site... early reports suggest the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the operation on Saturday evening and all the aircraft returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - enforced jihadist rule over significant areas in Syria and Iraq prior to its 2019 collapse.
"This strike shows British leadership, and determination to stand shoulder to shoulder with our allies, to eliminate any resurgence of IS and their violent and radical beliefs in the area," the British Defence Secretary the Defence Secretary said.
UK warplanes have conducted overwatch operations over Syrian airspace to "deter any efforts to regroup" of Islamic State following its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of British forces involved in this operation for their skill and their courage," Healey said. "Including them were thousands of UK service members deployed over the festive period. This mission, to take out terrorist threats who pose a risk to our security, highlights how UK forces are ready to step up, continuously, keeping Britain secure at home and influential overseas."
During December, the US military executed what it called a "large-scale strike" on IS targets in Syria, subsequent to an assault resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The UN says Islamic State still has between 5,000 and 7,000 combatants in Iraq and Syria.
