British Air Force Typhoon jets have operated alongside France's air force in a combined operation against an hidden munitions depot in Syrian territory operated by the Daesh militant organization, according to the UK's MoD.
The site, located using surveillance, was thought to be housing weapons and explosive materials, the release indicated, and was located in mountains just to the north of Palmyra in central Syria.
"Our fighter planes utilized Paveway IV guided bombs to hit a several approach shafts leading to the facility... preliminary assessments are that the strike was effective," the ministry announced.
There was no sign of any civilian casualties in the attack on Saturday evening and every plane involved returned safely, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
IS - alternatively referred to as Daesh - enforced jihadist rule over parts of both Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates British leadership, and determination to work closely with allied nations, to eliminate any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey remarked.
RAF aircraft have performed surveillance missions over Syria to "deter any attempted resurgence" of Islamic State following its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces involved in this strike for their expertise and their courage," the Defence Secretary commented. "They were among thousands of British troops deployed over the festive period. This mission, to remove militants who threaten our security, demonstrates how our armed forces are ready to step up, all year round, protecting the UK at home and strong abroad."
In December, the United States armed forces executed what it called a "massive strike" against Islamic State objectives in the country, following an attack killed two American soldiers and a civilian interpreter in Palmyra.
The UN estimates Daesh still boasts roughly 5-7 thousand combatants in both countries.
