British Air Force Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack on an underground arms cache in Syria used by the IS group, per a report from the UK Ministry of Defence.
The site, located using surveillance, was believed to be containing munitions and bombs, the statement said, and was positioned in mountains just to the north of Palmyra in Syria's central region.
"The RAF jets utilized Paveway IV guided bombs to target a number of access tunnels providing entry to the facility... early reports suggest the objective was successfully hit," the ministry announced.
There was no evidence of any civilian casualties in the attack conducted Saturday night and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - established militant control over significant areas in Syria and Iraq before its territorial defeat in 2019.

RAF aircraft have carried out patrols over Syria to "forestall any efforts to regroup" of Islamic State subsequent to its military defeat at the battle of Baghuz in the year 2019, the ministry said.
"I want to thank every member of the UK armed forces who took part in this strike for their expertise and their bravery," he commented. "They were among thousands of British personnel stationed over the festive period. This mission, to eliminate terrorist threats who endanger our security, shows how our armed forces are ready to step up, all year round, keeping Britain secure at home and powerful internationally."
