Royal Air Force Typhoon FGR4s have joined forces with French warplanes in a combined operation targeting an subterranean weapons facility in Syria used by the Daesh militant organization, as stated by the UK's MoD.
The facility, located using reconnaissance, was believed to be housing weapons and explosive materials, the announcement noted, and was situated in mountainous terrain just above Palmyra in the heart of Syria.
"Our fighter planes employed Paveway IV guided bombs to strike a number of entry passages providing entry to the site... preliminary assessments indicate the target was engaged successfully," the ministry announced.
There was no evidence of any civilian impact in the attack on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as Daesh - enforced extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This operation shows British leadership, and commitment to work closely with allied nations, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the region," the British Defence Secretary the minister stated.
UK warplanes have carried out patrols over Syria to "deter any attempted comeback" of the group after its routing at the battle of Baghuz in 2019, the ministry said.
"I must thank the personnel of our armed forces participating in this mission for their skill and their valour," Healey said. "Including them were a great many British troops on duty over the festive period. This action, to take out dangerous terrorists who threaten our safety, highlights how UK forces are ready to step up, continuously, protecting the UK at home and strong abroad."
During December, the US military carried out what it called a "large-scale strike" against Daesh sites in Syria, subsequent to an assault resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The United Nations estimates Islamic State still has roughly 5-7 thousand combatants in Syria and Iraq.
