RAF Typhoon FGR4s have operated alongside French warplanes in a coordinated attack against an subterranean weapons facility in Syrian territory operated by the Islamic State group (IS), as stated by the UK Ministry of Defence.
The site, pinpointed through surveillance, was assessed as storing arms and explosives, the release indicated, and was situated in mountainous terrain just north of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to hit a several approach shafts providing entry to the site... initial indications suggest the target was engaged successfully," the MoD said.
There was no evidence of any harm to civilians in the operation on Saturday evening and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - established militant control over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This strike underscores our UK leadership, and commitment to stand shoulder to shoulder with our partners, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed overwatch operations over Syria to "deter any attempted resurgence" of IS following its routing at the battle of Baghuz in 2019, the ministry said.
"I must thank the personnel of the UK armed forces who took part in this mission for their professionalism and their valour," he commented. "Including them were thousands of UK service members deployed over Christmas and New Year. This operation, to eliminate terrorist threats who threaten our safety, highlights how UK forces are prepared to act, all year round, protecting the UK domestically and powerful internationally."
In December, the US military carried out what it termed a "large-scale strike" against IS targets in Syria, subsequent to an attack resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The U.N. reports IS still has between 5,000 and 7,000 fighters in Syria and Iraq.
