RAF Typhoon jets have operated alongside France's air force in a coordinated attack against an underground arms cache in Syria operated by the Daesh militant organization, per a report from 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 the historic site of Palmyra in the heart of Syria.
"Our fighter planes employed Paveway IV guided bombs to target a several entry passages leading to the depot... early reports suggest the strike was effective," the MoD said.
There was no evidence of any harm to civilians in the operation conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The British jets were supported by a Voyager refuelling tanker.
Daesh - alternatively referred to as the so-called Islamic State - imposed extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike underscores the UK's leading role, and commitment to stand shoulder to shoulder with allied nations, to eradicate any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary John Healey remarked.
RAF aircraft have carried out overwatch operations over Syrian airspace to "forestall any attempted comeback" of the group after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank the personnel of the UK armed forces involved in this mission for their expertise and their courage," Healey commented. "They were part of thousands of British troops deployed over Christmas and New Year. This action, to remove dangerous terrorists who pose a risk to our safety, highlights how UK forces are prepared to act, continuously, keeping Britain secure at home and influential overseas."
Last December, the American forces executed what it termed a "major assault" against Islamic State objectives in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The United Nations estimates IS still maintains between 5,000 and 7,000 fighters in both countries.
