Royal Air Force Typhoon jets have joined forces with France's air force in a joint strike against an hidden munitions depot in Syria employed by the IS group, per a report from the UK's MoD.
The location, located using reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was located in hills just to the north of the ancient city of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to target a number of entry passages providing entry to the facility... initial indications suggest the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the operation late on Saturday and each participating jet made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
IS - referred to as ISIS - established militant control over large swathes of both Syria and Iraq until 2019.
"This action underscores British leadership, and determination to work closely with our partners, to eradicate any revival of Daesh and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister stated.
British military aircraft have performed overwatch operations over Syria to "forestall any attempted comeback" of IS after its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank every member of our armed forces who took part in this mission for their skill and their bravery," the Defence Secretary added. "They were part of numerous UK service members on duty over Christmas and New Year. This action, to remove militants who endanger our way of life, highlights how British military are always on standby, continuously, keeping Britain secure within its borders and influential overseas."
Last December, the American forces carried out what it called a "large-scale strike" against Daesh sites in the country, after an assault claimed the lives of two American soldiers and a civilian interpreter in the Palmyra area.
The UN says IS still has an estimated 5,000 to 7,000 militants in both countries.
