RAF Typhoon FGR4s 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's MoD.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the statement said, and was located in hills just north of Palmyra in the heart of Syria.
"The RAF jets used laser-guided Paveway IV weapons to target a several access tunnels providing entry to the site... preliminary assessments are that the target was engaged successfully," officials stated.
There was no sign of any civilian impact in the operation conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - enforced extremist governance over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This strike shows British leadership, and resolve to work closely with our partners, to eradicate any resurgence of IS and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary remarked.
RAF aircraft have conducted surveillance missions over Syrian airspace to "deter any efforts to regroup" of Islamic State after its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank the personnel of our armed forces who took part in this mission for their expertise and their bravery," he commented. "Including them were numerous British troops stationed over Christmas and New Year. This action, to take out terrorist threats who threaten our security, demonstrates how British military are prepared to act, throughout the year, protecting the UK domestically and strong abroad."
Last December, the United States armed forces executed what it called a "major assault" on IS targets in the country, following an assault resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN estimates Daesh still has an estimated 5,000 to 7,000 combatants in both countries.
