British Air Force Typhoon jets have operated alongside French warplanes in a combined operation against an hidden munitions depot in Syrian territory used by the IS group, per a report from the UK Ministry of Defence.
The facility, pinpointed through surveillance, was believed to be containing munitions and bombs, the release indicated, and was positioned in mountains just to the north of the ancient city of Palmyra in central Syria.
"The RAF jets utilized laser-guided Paveway IV weapons to strike a several access tunnels providing entry to the depot... preliminary assessments indicate the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the strike late on Saturday and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as Daesh - established extremist governance over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action shows the UK's leading role, and determination to work closely with our allies, to eradicate any revival of Daesh and their violent and radical beliefs in the area," UK Defence Secretary John Healey said.
British military aircraft have carried out overwatch operations over Syrian airspace to "deter any attempted resurgence" of IS following its military defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I must thank the personnel of our armed forces participating in this strike for their professionalism and their bravery," the Defence Secretary commented. "Including them were a great many British personnel stationed over the festive period. This action, to remove militants who threaten our security, demonstrates how our armed forces are prepared to act, continuously, protecting the UK within its borders and strong abroad."
In December, the American forces executed what it termed a "major assault" against Daesh sites in the country, following an assault claimed the lives of two American soldiers and a civilian linguist in Palmyra.
The UN says Daesh still boasts an estimated 5,000 to 7,000 militants in Syria and Iraq.
