Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a joint strike targeting an underground arms cache in Syrian territory operated by the Islamic State group (IS), as stated by the UK Ministry of Defence.
The facility, identified by reconnaissance, was thought to be storing arms and explosives, the statement said, and was situated in hills just above the historic site of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a several entry passages providing entry to the facility... initial indications indicate the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the strike conducted Saturday night and all the aircraft returned safely, the MoD added.
The Typhoon fighters were assisted by a Voyager tanker plane.
Daesh - referred to as ISIS - established militant control over parts of both Syria and Iraq until 2019.
"This strike underscores our UK leadership, and commitment to stand shoulder to shoulder with our allies, to stamp out any revival of Daesh and their harmful and extremist ideologies in the region," UK Defence Secretary the minister remarked.
RAF aircraft have performed patrols over Syrian airspace to "deter any attempted resurgence" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank the personnel of the UK armed forces involved in this strike for their expertise and their courage," he added. "They were part of a great many British personnel stationed over the festive period. This mission, to remove militants who pose a risk to our way of life, demonstrates how our armed forces are prepared to act, continuously, ensuring Britain's security within its borders and influential overseas."
Last December, the United States armed forces executed what it termed a "large-scale strike" against IS targets in Syria, after an assault killed two American soldiers and a civilian interpreter in the Palmyra area.
The UN reports IS still has between 5,000 and 7,000 combatants in Iraq and Syria.
