British Air Force Typhoon fighter aircraft have joined forces with France's air force in a combined operation against an subterranean weapons facility in Syria employed by the IS group, per a report from the British defence ministry.
The location, pinpointed through intelligence, was thought to be containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just above the ancient city of Palmyra in the heart of Syria.
"Our aircraft utilized precision-guided Paveway IV munitions to target a number of access tunnels providing entry to the depot... early reports are that the strike was effective," the MoD said.
There was no indication of any civilian casualties in the strike on Saturday evening and each participating jet returned safely, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - also known as ISIS - enforced extremist governance over significant areas in Iraq and Syria until 2019.
"This action demonstrates British leadership, and determination to operate in unison with our partners, to stamp out any revival of Daesh and their harmful and extremist ideologies in the region," the British Defence Secretary John Healey stated.
British military aircraft have conducted patrols over Syrian airspace to "forestall any efforts to regroup" of the group after its military defeat at the climactic battle in Baghuz in the year 2019, the ministry said.
"I want to thank all the members of our armed forces involved in this mission for their expertise and their valour," he added. "Including them were numerous British personnel deployed over Christmas and New Year. This mission, to remove militants who endanger our way of life, highlights how our armed forces are always on standby, all year round, keeping Britain secure within its borders and powerful internationally."
Last December, the United States armed forces carried out what it called a "large-scale strike" on Daesh sites in the country, following an assault resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The United Nations reports IS still maintains roughly 5-7 thousand combatants in both countries.
