RAF Typhoon jets have conducted a mission with French aircraft in a combined operation against an subterranean weapons facility in Syria employed by the Islamic State group (IS), as stated by the British defence ministry.
The site, pinpointed through intelligence, was believed to be containing munitions and bombs, the release indicated, and was located in mountainous terrain just north of the historic site of Palmyra in the heart of Syria.
"Our aircraft employed Paveway IV guided bombs to target a several approach shafts providing entry to the depot... early reports suggest the target was engaged successfully," the MoD said.
There was no sign of any civilian casualties in the attack on Saturday evening and every plane involved returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - also known as the so-called Islamic State - established extremist governance over large swathes of Iraq and Syria until 2019.
"This strike shows the UK's leading role, and determination to work closely with our allies, to stamp out any revival of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief John Healey remarked.
British military aircraft have conducted surveillance missions over Syria to "forestall any attempted comeback" of the group subsequent to its routing at the Baghuz confrontation in the year 2019, the ministry said.
"I want to thank every member of British forces participating in this mission for their expertise and their valour," he said. "They were among a great many British personnel stationed over the festive period. This operation, to remove terrorist threats who threaten our way of life, demonstrates how UK forces are always on standby, continuously, ensuring Britain's security domestically and influential overseas."
During December, the United States armed forces carried out what it described as a "major assault" targeting Islamic State objectives in the country, after an assault killed two US servicemembers and a civilian linguist in Palmyra.
The U.N. reports Islamic State still boasts roughly 5-7 thousand combatants in both countries.
