Royal Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a combined operation against an subterranean weapons facility in Syria operated by the IS group, per a report from the UK's MoD.
The location, identified by reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountains just north of the historic site of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to hit a number of approach shafts down to the site... initial indications are that the strike was effective," the ministry announced.
There was no evidence of any civilian impact in the attack on Saturday evening and every plane involved returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
Daesh - also known as Daesh - enforced extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This action underscores the UK's leading role, and commitment to operate in unison with our allies, to stamp out any revival of IS and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary said.
British military aircraft have performed surveillance missions over Syria to "forestall any attempted resurgence" of Islamic State following its routing at the battle of Baghuz in the year 2019, the ministry said.
"I must thank the personnel of British forces participating in this mission for their skill and their bravery," the Defence Secretary said. "They were part of thousands of British troops on duty over the holidays. This action, to eliminate dangerous terrorists who threaten our way of life, demonstrates how our armed forces are prepared to act, continuously, keeping Britain secure within its borders and influential overseas."
During December, the American forces executed what it called a "large-scale strike" targeting Islamic State objectives in Syria, following an attack claimed the lives of two American soldiers and a civilian interpreter in Palmyra.
The United Nations says Islamic State still has an estimated 5,000 to 7,000 militants in Syria and Iraq.
