British Air Force Typhoon fighter aircraft have joined forces with France's air force in a combined operation targeting an subterranean weapons facility in Syrian territory employed by the IS group, as stated by the British defence ministry.
The site, located using surveillance, was thought to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just north of Palmyra in central Syria.
"Our aircraft employed Paveway IV guided bombs to hit a several approach shafts leading to the depot... initial indications are that the strike was effective," the ministry announced.
There was no indication of any harm to civilians in the strike conducted Saturday night 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 the so-called Islamic State - enforced extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This strike underscores the UK's leading role, and resolve to work closely with our partners, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," the British Defence Secretary John Healey said.
British military aircraft have conducted patrols over Syrian airspace to "deter any attempted comeback" of the group following its defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I must thank the personnel of the UK armed forces who took part in this strike for their professionalism and their bravery," he said. "They were part of numerous UK service members deployed over the festive period. This mission, to take out militants who pose a risk to our safety, shows how British military are ready to step up, all year round, protecting the UK domestically and strong abroad."
Last December, the US military conducted what it termed a "massive strike" against Islamic State objectives in the country, after an attack claimed the lives of two US troops and a civilian linguist in Palmyra.
The U.N. says Islamic State still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
