Royal Air Force Typhoon FGR4s have joined forces with France's air force in a coordinated attack against an subterranean weapons facility in Syria employed by the IS group, according to the UK's MoD.
The facility, located using reconnaissance, was assessed as storing arms and explosives, the statement said, and was positioned in mountainous terrain just above Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a number of entry passages down to the site... early reports indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the operation conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were supported by a Voyager refuelling tanker.
Daesh - alternatively referred to as ISIS - established jihadist rule over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action shows the UK's leading role, and commitment to stand shoulder to shoulder with allied nations, to stamp out any resurgence of IS and their violent and radical beliefs in the area," the British Defence Secretary the minister remarked.
British military aircraft have conducted patrols over Syrian airspace to "deter any attempted resurgence" of IS after its military defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank the personnel of the UK armed forces involved in this strike for their professionalism and their courage," Healey said. "They were among a great many UK service members on duty over the holidays. This operation, to take out dangerous terrorists who threaten our security, demonstrates how our armed forces are always on standby, all year round, protecting the UK domestically and strong abroad."
Last December, the United States armed forces carried out what it termed a "massive strike" targeting Islamic State objectives in Syria, following an ambush killed two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations estimates IS still has roughly 5-7 thousand militants in Syria and Iraq.
