Royal Air Force Typhoon jets have conducted a mission with France's air force in a combined operation against an underground arms cache in Syrian territory used by the Daesh militant organization, as stated by the British defence ministry.
The location, located using reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was situated in mountains just above the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to hit a several entry passages leading to the facility... early reports are that the strike was effective," officials stated.
There was no sign of any harm to civilians in the attack on Saturday evening and every plane involved returned safely, the ministry further stated.
The British jets were supported by a Voyager tanker plane.
Daesh - referred to as Daesh - enforced jihadist rule over large swathes of Iraq and Syria prior to its 2019 collapse.
"This operation shows British leadership, and determination to operate in unison with our partners, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the Middle East," the British Defence Secretary John Healey said.
RAF aircraft have carried out overwatch operations over Syria to "prevent any attempted resurgence" of the group after its routing at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of British forces involved in this operation for their skill and their valour," he added. "They were among numerous UK service members stationed over the holidays. This mission, to remove terrorist threats who endanger our safety, highlights how British military are prepared to act, continuously, protecting the UK within its borders and powerful internationally."
During December, the American forces carried out what it termed a "major assault" targeting Islamic State objectives in the country, after an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The U.N. estimates IS still has between 5,000 and 7,000 combatants in both countries.
