RAF Typhoon jets have conducted a mission with French warplanes in a coordinated attack on an hidden munitions depot in Syria employed by the IS group, as stated by the British defence ministry.
The facility, located using intelligence, was thought to be containing munitions and bombs, the release indicated, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a series of access tunnels providing entry to the depot... preliminary assessments indicate the strike was effective," the ministry announced.
There was no evidence of any harm to civilians in the operation conducted Saturday night and all the aircraft returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - established jihadist rule over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation underscores our UK leadership, and determination to operate in unison with our allies, to eliminate any re-emergence of IS and their violent and radical beliefs in the area," UK Defence Secretary the minister remarked.
British military aircraft have performed surveillance missions over Syrian airspace to "prevent any attempted comeback" of IS after its routing at the climactic battle in Baghuz in the year 2019, the ministry said.
"I must thank every member of British forces who took part in this strike for their expertise and their bravery," the Defence Secretary said. "They were part of a great many British troops stationed over the festive period. This mission, to remove militants who threaten our safety, highlights how British military are always on standby, continuously, ensuring Britain's security domestically and influential overseas."
In December, the United States armed forces carried out what it called a "massive strike" on Daesh sites in the country, subsequent to an attack claimed the lives of two American soldiers and a civilian interpreter in the Palmyra area.
The United Nations estimates Daesh still has roughly 5-7 thousand fighters in both countries.
