Royal Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack on an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The facility, identified by intelligence, was believed to be storing arms and explosives, the release indicated, and was positioned in mountainous terrain just to the north of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to hit a number of entry passages leading to the site... initial indications indicate the strike was effective," the MoD said.
There was no evidence of any civilian impact in the attack conducted Saturday night and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - established jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This action underscores the UK's leading role, and determination to work closely with our partners, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the region," Britain's Defence Chief John Healey remarked.
UK warplanes have performed overwatch operations over Syria to "forestall any efforts to regroup" of the group following its routing at the battle of Baghuz in 2019, the authorities noted.
"I must thank all the members of British forces involved in this strike for their skill and their bravery," he commented. "They were part of a great many British troops stationed over the holidays. This action, to eliminate dangerous terrorists who endanger our security, highlights how our armed forces are ready to step up, all year round, keeping Britain secure at home and strong abroad."
During December, the US military carried out what it called a "large-scale strike" against Islamic State objectives in the country, subsequent to an assault claimed the lives of two American soldiers and a local interpreter in Palmyra.
The United Nations estimates IS still maintains roughly 5-7 thousand militants in Syria and Iraq.
