British Air Force Typhoon FGR4s have joined forces with France's air force in a joint strike on an subterranean weapons facility in Syria operated by the IS group, per a report from the British defence ministry.
The site, identified by intelligence, was believed to be storing arms and explosives, the release indicated, and was located in hills just north of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to target a number of entry passages leading to the site... initial indications are that the target was engaged successfully," the ministry announced.
There was no indication of any civilian impact in the strike late on Saturday and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as ISIS - established jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This action underscores the UK's leading role, and determination to operate in unison with our allies, to eradicate any re-emergence of Daesh and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary said.
RAF aircraft have performed surveillance missions over Syria to "forestall any attempted resurgence" of IS subsequent to its defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I want to thank the personnel of British forces participating in this strike for their expertise and their courage," the Defence Secretary said. "Including them were numerous British troops deployed over Christmas and New Year. This mission, to eliminate dangerous terrorists who pose a risk to our way of life, demonstrates how our armed forces are prepared to act, all year round, protecting the UK within its borders and strong abroad."
Last December, the American forces executed what it termed a "massive strike" against IS targets in Syria, after an ambush resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The UN estimates Islamic State still has an estimated 5,000 to 7,000 militants in Iraq and Syria.
