RAF Typhoon jets have joined forces with French aircraft in a joint strike against an subterranean weapons facility in Syrian territory used by the IS group, per a report from the British defence ministry.
The location, located using intelligence, was thought to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a number of entry passages down to the depot... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the operation late on Saturday and all the aircraft returned safely, the defence officials confirmed.
The British jets were backed up by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - enforced militant control over significant areas in Iraq and Syria until 2019.
"This strike underscores the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to eradicate any re-emergence of IS and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the minister remarked.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any efforts to regroup" of IS following its routing at the Baghuz confrontation in 2019, the ministry said.
"I must thank every member of our armed forces involved in this mission for their skill and their bravery," he added. "They were among thousands of British troops deployed over the holidays. This action, to remove dangerous terrorists who pose a risk to our way of life, shows how UK forces are always on standby, continuously, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces conducted what it described as a "major assault" on Daesh sites in the country, subsequent to an assault claimed the lives of two US servicemembers and a civilian interpreter in the Palmyra area.
The UN reports Islamic State still boasts an estimated 5,000 to 7,000 combatants in Iraq and Syria.
