Royal Air Force Typhoon jets have joined forces with France's air force in a joint strike against an subterranean weapons facility in Syria operated by the IS group, per a report from the UK's MoD.
The site, identified by reconnaissance, was assessed as containing munitions and bombs, the statement said, and was situated in mountainous terrain just above the historic site of Palmyra in central Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a series of approach shafts providing entry to the site... initial indications are that the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the attack on Saturday evening and each participating jet returned to base without incident, the ministry further stated.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - imposed militant control over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike demonstrates the UK's leading role, and commitment to work closely with our partners, to eradicate any re-emergence of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary the minister stated.
RAF aircraft have carried out patrols over Syria to "prevent any efforts to regroup" of IS after its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank every member of our armed forces involved in this strike for their professionalism and their courage," the Defence Secretary commented. "They were among numerous British troops deployed over Christmas and New Year. This mission, to take out terrorist threats who pose a risk to our safety, demonstrates how UK forces are always on standby, continuously, protecting the UK domestically and powerful internationally."
Last December, the American forces executed what it termed a "major assault" against Islamic State objectives in the country, after an ambush killed two American soldiers and a civilian interpreter in Palmyra.
The UN reports IS still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
