Royal Air Force Typhoon FGR4s have joined forces with French warplanes in a coordinated attack against an subterranean weapons facility in Syria used by the IS group, as stated by the UK's MoD.
The site, located using surveillance, was assessed as storing arms and explosives, the announcement noted, and was situated in hills just above Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a several access tunnels leading to the site... early reports are that the objective was successfully hit," officials stated.
There was no indication of any civilian impact in the operation on Saturday evening and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - established jihadist rule over significant areas in Iraq and Syria until 2019.
"This strike shows British leadership, and determination to operate in unison with our partners, to stamp out any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary John Healey remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "forestall any efforts to regroup" of Islamic State after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their skill and their courage," the Defence Secretary commented. "Including them were a great many British troops on duty over Christmas and New Year. This action, to eliminate dangerous terrorists who pose a risk to our way of life, shows how British military are always on standby, all year round, keeping Britain secure domestically and strong abroad."
In December, the American forces carried out what it called a "large-scale strike" on IS targets in Syria, after an assault killed two US servicemembers and a civilian linguist in Palmyra.
The United Nations estimates Islamic State still boasts roughly 5-7 thousand militants in Syria and Iraq.
