British Air Force Typhoon fighter aircraft have operated alongside France's air force in a combined operation targeting an underground arms cache in Syria operated by the IS group, per a report from the UK Ministry of Defence.
The facility, located using reconnaissance, was thought to be storing arms and explosives, the announcement noted, and was located in hills just north of the ancient city of Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to strike a series of entry passages providing entry to the site... preliminary assessments indicate the strike was effective," officials stated.
There was no indication of any civilian impact in the strike conducted Saturday night and all the aircraft returned to base without incident, the MoD added.
The British jets were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - enforced extremist governance over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation underscores our UK leadership, and resolve to work closely with our partners, to eradicate any re-emergence of Daesh and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed patrols over Syria to "deter any attempted comeback" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank the personnel of our armed forces who took part in this operation for their expertise and their courage," the Defence Secretary added. "Including them were a great many British troops on duty over Christmas and New Year. This mission, to eliminate militants who endanger our safety, highlights how our armed forces are ready to step up, continuously, protecting the UK within its borders and influential overseas."
During December, the US military conducted what it termed a "massive strike" on Islamic State objectives in Syria, subsequent to an assault resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The U.N. reports Daesh still boasts between 5,000 and 7,000 combatants in both countries.
