Royal Air Force Typhoon fighter aircraft have operated alongside France's air force in a joint strike on an subterranean weapons facility in Syrian territory employed by the Islamic State group (IS), according to the UK Ministry of Defence.
The location, located using intelligence, was believed to be storing arms and explosives, the announcement noted, and was positioned in mountains just to the north of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to target a series of access tunnels down to the facility... preliminary assessments indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the attack on Saturday evening and every plane involved returned safely, the MoD added.
The British jets were backed up by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - established militant control over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This action underscores our UK leadership, and determination to work closely with allied nations, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the area," Britain's Defence Chief the minister remarked.
RAF aircraft have performed surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank the personnel of British forces who took part in this mission for their professionalism and their courage," Healey commented. "They were among a great many British troops deployed over the holidays. This mission, to eliminate terrorist threats who pose a risk to our safety, shows how British military are always on standby, all year round, ensuring Britain's security domestically and powerful internationally."
Last December, the US military executed what it termed a "massive strike" targeting Islamic State objectives in the country, following an assault claimed the lives of two American soldiers and a civilian interpreter in the Palmyra area.
The UN estimates IS still has an estimated 5,000 to 7,000 militants in both countries.
