British Air Force Typhoon FGR4s have joined forces with French warplanes in a joint strike against an subterranean weapons facility in Syria employed by the Daesh militant organization, as stated by the UK's MoD.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the statement said, and was positioned in mountainous terrain just north of Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to target a number of approach shafts down to the site... preliminary assessments indicate the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike on Saturday evening and all the aircraft returned to base without incident, the MoD added.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - imposed jihadist rule over large swathes of Iraq and Syria until 2019.
"This strike underscores the UK's leading role, and determination to stand shoulder to shoulder with our partners, to stamp out any re-emergence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary stated.
UK warplanes have carried out patrols over Syria to "deter any attempted resurgence" of Islamic State subsequent to its routing at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of the UK armed forces who took part in this operation for their professionalism and their courage," Healey said. "They were part of a great many British troops on duty over the festive period. This mission, to take out terrorist threats who threaten our way of life, demonstrates how our armed forces are prepared to act, continuously, protecting the UK at home and strong abroad."
In December, the United States armed forces conducted what it termed a "large-scale strike" against Islamic State objectives in Syria, subsequent to an assault resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The U.N. says Islamic State still has roughly 5-7 thousand fighters in both countries.
