RAF Typhoon FGR4s have joined forces with French warplanes in a combined operation against an subterranean weapons facility in Syrian territory used by the IS group, as stated by the British defence ministry.
The site, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the announcement noted, and was positioned in mountainous terrain just above the historic site of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a several approach shafts providing entry to the facility... initial indications indicate the strike was effective," the MoD said.
There was no sign of any civilian casualties in the strike on Saturday evening and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - also known as the so-called Islamic State - enforced jihadist rule over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This action demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to eradicate any revival of the terrorist group and their violent and radical beliefs in the area," UK Defence Secretary the Defence Secretary said.
British military aircraft have conducted overwatch operations over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I must thank every member of our armed forces participating in this strike for their professionalism and their courage," he commented. "They were among thousands of UK service members stationed over the holidays. This action, to eliminate dangerous terrorists who pose a risk to our security, highlights how UK forces are ready to step up, continuously, protecting the UK domestically and strong abroad."
Last December, the United States armed forces executed what it called a "large-scale strike" targeting Islamic State objectives in Syria, subsequent to an ambush resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The UN reports IS still boasts roughly 5-7 thousand combatants in Iraq and Syria.
