Royal Air Force Typhoon jets have joined forces with French warplanes in a joint strike targeting an subterranean weapons facility in Syria employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, identified by surveillance, was assessed as storing arms and explosives, the statement said, and was situated in hills just north of Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a number of access tunnels down to the facility... early reports are that the strike was effective," officials stated.
There was no evidence of any harm to civilians in the operation on Saturday evening and all the aircraft returned safely, the defence officials confirmed.
The British jets were supported by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - enforced militant control over parts of both Syria and Iraq until 2019.
"This operation shows British leadership, and resolve to operate in unison with our partners, to stamp out any resurgence of IS and their harmful and extremist ideologies in the region," UK Defence Secretary the Defence Secretary stated.
RAF aircraft have carried out patrols over Syrian airspace to "forestall any attempted resurgence" of IS following its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I want to thank all the members of the UK armed forces who took part in this mission for their skill and their courage," he commented. "They were among thousands of UK service members stationed over the festive period. This mission, to remove dangerous terrorists who threaten our security, highlights how our armed forces are always on standby, all year round, keeping Britain secure within its borders and influential overseas."
In December, the American forces conducted what it called a "major assault" against Islamic State objectives in Syria, after an assault resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The UN says IS still has between 5,000 and 7,000 combatants in Syria and Iraq.
