Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a coordinated attack on an hidden munitions depot in Syria operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, identified by reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was located in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes used precision-guided Paveway IV munitions to hit a number of entry passages providing entry to the site... early reports are that the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the attack late on Saturday and every plane involved returned safely, the defence officials confirmed.
The British jets were assisted by a Voyager refuelling tanker.
IS - referred to as Daesh - established extremist governance over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike demonstrates the UK's leading role, and resolve to work closely with our partners, to stamp out any revival of IS and their violent and radical beliefs in the region," Britain's Defence Chief John Healey said.
UK warplanes have performed surveillance missions over Syrian airspace to "prevent any attempted resurgence" of the group subsequent to its routing at the climactic battle in Baghuz in the year 2019, the ministry said.
"I extend gratitude to every member of our armed forces involved in this mission for their expertise and their courage," the Defence Secretary added. "Including them were numerous British troops deployed over the festive period. This operation, to take out terrorist threats who threaten our way of life, shows how British military are prepared to act, all year round, protecting the UK domestically and influential overseas."
In December, the American forces carried out what it described as a "major assault" targeting IS targets in the country, subsequent to an ambush claimed the lives of two US servicemembers and a civilian interpreter in the Palmyra area.
The UN says IS still has between 5,000 and 7,000 fighters in Iraq and Syria.
