Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a joint strike against an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), according to the UK's MoD.
The facility, located using surveillance, was believed to be containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just north of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a number of access tunnels providing entry to the facility... initial indications suggest the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the attack late on Saturday and each participating jet returned to base without incident, the MoD added.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - imposed jihadist rule over significant areas in Syria and Iraq prior to its 2019 collapse.
"This strike shows our UK leadership, and resolve to operate in unison with our allies, to eliminate any re-emergence of IS and their violent and radical beliefs in the Middle East," Britain's Defence Chief the minister remarked.
UK warplanes have carried out surveillance missions over Syria to "forestall any attempted resurgence" of the group after its routing at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank the personnel of the UK armed forces involved in this mission for their skill and their valour," the Defence Secretary added. "They were among a great many UK service members on duty over the holidays. This operation, to eliminate terrorist threats who threaten our way of life, shows how our armed forces are ready to step up, all year round, protecting the UK at home and influential overseas."
During December, the American forces executed what it described as a "large-scale strike" against Daesh sites in Syria, following an ambush resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The UN says Islamic State still has roughly 5-7 thousand fighters in Syria and Iraq.
