RAF Typhoon fighter aircraft have joined forces with French aircraft in a joint strike against an underground arms cache in Syrian territory operated by the Daesh militant organization, as stated by the UK Ministry of Defence.
The location, located using intelligence, was believed to be containing munitions and bombs, the release indicated, and was situated in mountains just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft utilized precision-guided Paveway IV munitions to hit a number of entry passages leading to the depot... preliminary assessments suggest the strike was effective," officials stated.
There was no sign of any civilian casualties in the attack on Saturday evening and each participating jet returned safely, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as the so-called Islamic State - established extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This strike shows British leadership, and determination to operate in unison with our allies, to stamp out any resurgence of Daesh and their violent and radical beliefs in the region," Britain's Defence Chief John Healey said.
UK warplanes have carried out surveillance missions over Syrian airspace to "deter any attempted resurgence" of Islamic State following its routing at the battle of Baghuz in the year 2019, the MoD reported.
"I must thank all the members of British forces participating in this mission for their professionalism and their courage," the Defence Secretary added. "They were among a great many British troops deployed over the holidays. This operation, to remove militants who pose a risk to our security, demonstrates how British military are always on standby, continuously, protecting the UK within its borders and strong abroad."
During December, the US military executed what it called a "massive strike" on Daesh sites in the country, following an ambush killed two US troops and a civilian linguist in the Palmyra area.
The UN says Islamic State still has between 5,000 and 7,000 combatants in both countries.
