Royal Air Force Typhoon jets have joined forces with France's air force in a combined operation targeting an hidden munitions depot in Syrian territory operated by the IS group, as stated by the UK's MoD.
The facility, pinpointed through intelligence, was thought to be storing arms and explosives, the release indicated, and was located in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a number of access tunnels leading to the site... initial indications suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the operation on Saturday evening and every plane involved returned safely, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - enforced militant control over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This operation underscores the UK's leading role, and resolve to work closely with allied nations, to eradicate any resurgence of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary John Healey remarked.
RAF aircraft have performed patrols over Syria to "deter any efforts to regroup" of IS after its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to the personnel of British forces who took part in this operation for their expertise and their bravery," the Defence Secretary added. "They were among numerous British personnel deployed over Christmas and New Year. This operation, to remove dangerous terrorists who pose a risk to our way of life, highlights how UK forces are ready to step up, continuously, ensuring Britain's security domestically and influential overseas."
In December, the American forces executed what it termed a "major assault" targeting Daesh sites in the country, after an assault killed two American soldiers and a civilian linguist in the Palmyra area.
The U.N. says IS still boasts between 5,000 and 7,000 militants in Iraq and Syria.
