RAF Typhoon FGR4s have conducted a mission with France's air force in a combined operation on an subterranean weapons facility in Syrian territory employed by the Islamic State group (IS), according to the British defence ministry.
The location, located using surveillance, was believed to be containing munitions and bombs, the release indicated, and was situated in hills just to the north of Palmyra in the heart of Syria.
"The RAF jets used laser-guided Paveway IV weapons to target a series of access tunnels providing entry to the facility... preliminary assessments indicate the strike was effective," the MoD said.
There was no evidence of any civilian impact in the operation on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - established militant control over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation shows our UK 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 Middle East," Britain's Defence Chief the Defence Secretary said.
UK warplanes have conducted overwatch operations over Syrian airspace to "deter any attempted resurgence" of the group following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank all the members of the UK armed forces participating in this mission for their skill and their valour," Healey added. "They were among thousands of UK service members stationed over Christmas and New Year. This mission, to remove terrorist threats who pose a risk to our safety, demonstrates how British military are ready to step up, throughout the year, keeping Britain secure at home and influential overseas."
In December, the United States armed forces executed what it termed a "major assault" targeting Islamic State objectives in Syria, subsequent to an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The U.N. estimates Islamic State still boasts roughly 5-7 thousand militants in Iraq and Syria.
