British Air Force Typhoon fighter aircraft have operated alongside France's air force in a coordinated attack against an subterranean weapons facility in Syrian territory operated by the IS group, per a report from the British defence ministry.
The facility, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the announcement noted, and was located in mountains just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to hit a several approach shafts leading to the site... early reports suggest the target was engaged successfully," officials stated.
There was no indication of any civilian casualties in the attack late on Saturday and every plane involved returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as Daesh - established militant control over parts of both Syria and Iraq before its territorial defeat in 2019.
"This operation underscores British leadership, and resolve to operate in unison with allied nations, to stamp out any revival of Daesh and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the minister remarked.
UK warplanes have conducted surveillance missions over Syrian airspace to "deter any attempted resurgence" of IS after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank the personnel of the UK armed forces participating in this operation for their expertise and their bravery," Healey added. "Including them were thousands of UK service members stationed over Christmas and New Year. This action, to remove dangerous terrorists who endanger our safety, highlights how British military are prepared to act, throughout the year, ensuring Britain's security domestically and influential overseas."
Last December, the American forces carried out what it described as a "major assault" on IS targets in the country, following an ambush claimed the lives of two American soldiers and a civilian linguist in Palmyra.
The United Nations estimates IS still maintains roughly 5-7 thousand combatants in both countries.
