RAF Typhoon fighter aircraft have joined forces with France's air force in a combined operation against an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), as stated by the British defence ministry.
The location, pinpointed through surveillance, was thought to be storing arms and explosives, the statement said, and was located in mountainous terrain just above Palmyra in central Syria.
"The RAF jets employed precision-guided Paveway IV munitions to hit a series of access tunnels down to the facility... early reports indicate the strike was effective," officials stated.
There was no sign of any harm to civilians in the attack conducted Saturday night and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - referred to as Daesh - established jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This strike underscores our UK leadership, and resolve to work closely with our allies, to stamp out any re-emergence of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief the Defence Secretary stated.
RAF aircraft have conducted patrols over Syrian airspace to "forestall any efforts to regroup" of Islamic State subsequent to its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank the personnel of British forces involved in this operation for their skill and their courage," he added. "They were among numerous UK service members deployed over Christmas and New Year. This operation, to eliminate terrorist threats who endanger our safety, demonstrates how UK forces are prepared to act, all year round, protecting the UK within its borders and powerful internationally."
During December, the US military executed what it termed a "major assault" against Daesh sites in Syria, following an attack claimed the lives of two US troops and a local interpreter in the Palmyra area.
The United Nations says Daesh still has between 5,000 and 7,000 combatants in Syria and Iraq.
