British Air Force Typhoon FGR4s have conducted a mission with France's air force in a combined operation targeting an underground arms cache in Syrian territory employed by the IS group, as stated by the British defence ministry.
The facility, identified by surveillance, was believed to be storing arms and explosives, the announcement noted, and was located in mountains just north of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to strike a several access tunnels leading to the depot... initial indications indicate the strike was effective," officials stated.
There was no indication of any civilian impact in the strike late on Saturday and every plane involved returned safely, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as ISIS - established jihadist rule over parts of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores our UK leadership, and determination to operate in unison with allied nations, to stamp out any re-emergence of the terrorist group and their dangerous and violent ideologies in the region," Britain's Defence Chief John Healey said.
British military aircraft have carried out surveillance missions over Syria to "forestall any attempted resurgence" of the group subsequent to its routing at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I extend gratitude to the personnel of our armed forces participating in this mission for their skill and their courage," the Defence Secretary commented. "They were part of thousands of British troops deployed over Christmas and New Year. This operation, to take out dangerous terrorists who pose a risk to our way of life, highlights how British military are always on standby, continuously, keeping Britain secure at home and influential overseas."
Last December, the United States armed forces conducted what it called a "large-scale strike" against Daesh sites in the country, after an attack resulted in the deaths of two US troops and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still boasts roughly 5-7 thousand fighters in Iraq and Syria.
