RAF Typhoon FGR4s have joined forces with French aircraft in a combined operation targeting an hidden munitions depot in Syrian territory operated by the IS group, according to the British defence ministry.
The facility, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountains just above the historic site of Palmyra in Syria's central region.
"Our fighter planes used Paveway IV guided bombs to strike a number of access tunnels down to the facility... preliminary assessments suggest the strike was effective," officials stated.
There was no sign of any civilian impact in the attack late on Saturday and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were supported by a Voyager tanker plane.
The Islamic State group - also known as ISIS - established jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This strike underscores the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to eradicate any revival of Daesh and their violent and radical beliefs in the area," Britain's Defence Chief the minister remarked.
RAF aircraft have conducted surveillance missions over Syrian airspace to "deter any efforts to regroup" of the group following its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to every member of our armed forces involved in this strike for their professionalism and their valour," Healey commented. "They were among thousands of UK service members stationed over the holidays. This mission, to take out militants who endanger our way of life, demonstrates how our armed forces are ready to step up, all year round, keeping Britain secure within its borders and strong abroad."
During December, the US military carried out what it called a "major assault" against Daesh sites in the country, subsequent to an assault resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The UN says Daesh still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
