RAF Typhoon jets have operated alongside France's air force in a coordinated attack against an subterranean weapons facility in Syria operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, located using surveillance, was thought to be containing munitions and bombs, the statement said, and was positioned in mountains just to the north of the ancient city of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to target a series of entry passages providing entry to the facility... early reports are that the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the attack conducted Saturday night 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 - also known as Daesh - enforced militant control over parts of Iraq and Syria until 2019.
"This strike shows the UK's leading role, and resolve to operate in unison with our partners, to eliminate any re-emergence of IS and their harmful and extremist ideologies in the area," the British Defence Secretary the Defence Secretary remarked.
UK warplanes have performed surveillance missions over Syrian airspace to "deter any attempted resurgence" of IS following its routing at the battle of Baghuz in 2019, the ministry said.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their expertise and their courage," the Defence Secretary said. "They were among thousands of British troops stationed over the holidays. This action, to remove militants who endanger our security, shows how our armed forces are prepared to act, continuously, keeping Britain secure at home and influential overseas."
During December, the US military carried out what it described as a "massive strike" against Daesh sites in Syria, subsequent to an attack killed two American soldiers and a civilian linguist in Palmyra.
The U.N. says Daesh still boasts an estimated 5,000 to 7,000 fighters in both countries.
