RAF Typhoon FGR4s have operated alongside French warplanes in a joint strike targeting an subterranean weapons facility in Syrian territory used by the Islamic State group (IS), per a report from the British defence ministry.
The location, identified by surveillance, was believed to be storing arms and explosives, the statement said, and was located in hills just to the north of the historic site of Palmyra in central Syria.
"The RAF jets employed Paveway IV guided bombs to hit a number of approach shafts providing entry to the depot... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the strike conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as the so-called Islamic State - enforced extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This strike underscores the UK's leading role, and determination to stand shoulder to shoulder with our partners, to eradicate any revival of Daesh and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary said.
UK warplanes have performed overwatch operations over Syria to "deter any attempted resurgence" of IS subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank every member of our armed forces involved in this operation for their professionalism and their bravery," he commented. "Including them were thousands of British troops stationed over Christmas and New Year. This action, to eliminate terrorist threats who endanger our way of life, shows how British military are ready to step up, throughout the year, keeping Britain secure domestically and powerful internationally."
During December, the United States armed forces executed what it termed a "massive strike" on Daesh sites in the country, after an assault claimed the lives of two US troops and a local interpreter in Palmyra.
The U.N. estimates Daesh still has between 5,000 and 7,000 combatants in both countries.
