British Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation targeting an underground arms cache in Syrian territory employed by the Daesh militant organization, as stated by the UK's MoD.
The location, identified by reconnaissance, was thought to be storing arms and explosives, the release indicated, and was located in mountainous terrain just north of Palmyra in Syria's central region.
"Our aircraft utilized Paveway IV guided bombs to target a several approach shafts leading to the site... initial indications suggest the objective was successfully hit," the ministry announced.
There was no sign of any civilian casualties in the strike conducted Saturday night and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - also known as ISIS - imposed jihadist rule over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This action shows our UK leadership, and resolve to work closely with our partners, to eliminate any re-emergence of Daesh and their harmful and extremist ideologies in the area," the British Defence Secretary the minister said.
RAF aircraft have conducted patrols over Syria to "prevent any attempted resurgence" of Islamic State subsequent to its military defeat at the battle of Baghuz in 2019, the authorities noted.
"I must thank all the members of British forces involved in this mission for their skill and their valour," he commented. "Including them were numerous British troops deployed over the holidays. This operation, to take out dangerous terrorists who threaten our way of life, shows how British military are prepared to act, all year round, keeping Britain secure domestically and influential overseas."
In December, the United States armed forces carried out what it termed a "large-scale strike" on Islamic State objectives in Syria, subsequent to an ambush killed two US troops and a local interpreter in the Palmyra area.
The United Nations says IS still boasts roughly 5-7 thousand combatants in both countries.
