Royal Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation targeting an subterranean weapons facility in Syria operated by the Daesh militant organization, according to the UK Ministry of Defence.
The site, identified by intelligence, was believed to be containing munitions and bombs, the announcement noted, and was located in mountainous terrain just to the north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes employed precision-guided Paveway IV munitions to strike a number of approach shafts down to the depot... early reports suggest the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the attack on Saturday evening and every plane involved returned safely, the MoD added.
The British jets were backed up by a Voyager tanker plane.
Daesh - referred to as ISIS - established extremist governance over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and determination to work closely with our partners, to eliminate any revival of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister stated.
RAF aircraft have carried out overwatch operations over Syria to "forestall any attempted resurgence" of Islamic State subsequent to its military defeat at the climactic battle in Baghuz in the year 2019, the ministry said.
"I want to thank the personnel of the UK armed forces involved in this operation for their skill and their courage," he commented. "They were part of thousands of British troops stationed over the festive period. This operation, to eliminate militants who pose a risk to our way of life, demonstrates how our armed forces are ready to step up, continuously, keeping Britain secure at home and influential overseas."
Last December, the US military executed what it described as a "massive strike" on IS targets in Syria, subsequent to an ambush claimed the lives of two American soldiers and a civilian interpreter in Palmyra.
The UN says Daesh still has an estimated 5,000 to 7,000 combatants in Iraq and Syria.
