British Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack against an hidden munitions depot in Syria operated by the Daesh militant organization, according to the UK's MoD.
The facility, pinpointed through intelligence, was thought to be containing munitions and bombs, the announcement noted, and was located in mountains just above the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to target a series of approach shafts leading to the site... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the strike late on Saturday and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were supported by a Voyager refuelling tanker.
Daesh - referred to as ISIS - enforced militant control over large swathes of Iraq and Syria until 2019.
"This operation underscores our UK leadership, and determination to operate in unison with our partners, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary remarked.
RAF aircraft have performed patrols over Syria to "prevent any attempted comeback" of IS following its routing at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank all the members of our armed forces participating in this mission for their expertise and their valour," Healey added. "Including them were thousands of UK service members on duty over Christmas and New Year. This mission, to take out dangerous terrorists who endanger our security, demonstrates how British military are prepared to act, throughout the year, ensuring Britain's security domestically and influential overseas."
In December, the American forces conducted what it termed a "major assault" on Islamic State objectives in the country, following an ambush claimed the lives of two American soldiers and a local interpreter in Palmyra.
The United Nations reports IS still has roughly 5-7 thousand fighters in Syria and Iraq.
