Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a joint strike on an hidden munitions depot in Syrian territory used by the Islamic State group (IS), according to the UK's MoD.
The site, located using surveillance, was believed to be storing arms and explosives, the release indicated, and was positioned in mountains just to the north of the historic site of Palmyra in central Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to strike a number of approach shafts down to the depot... initial indications suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as ISIS - established militant control over significant areas in Iraq and Syria until 2019.
"This operation underscores British leadership, and commitment to stand shoulder to shoulder with our partners, to eliminate any revival of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary stated.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State subsequent to its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank every member of British forces participating in this mission for their professionalism and their valour," the Defence Secretary commented. "They were among thousands of British troops on duty over the festive period. This action, to take out dangerous terrorists who pose a risk to our way of life, shows how our armed forces are prepared to act, throughout the year, ensuring Britain's security domestically and powerful internationally."
Last December, the American forces executed what it described as a "large-scale strike" on IS targets in the country, after an ambush killed two US servicemembers and a local interpreter in Palmyra.
The UN reports Daesh still has between 5,000 and 7,000 fighters in Syria and Iraq.
