RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a coordinated attack against an hidden munitions depot in Syria operated by the Daesh militant organization, as stated by the British defence ministry.
The facility, located using reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was positioned in mountains just above Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to target a several access tunnels providing entry to the facility... early reports are that the objective was successfully hit," the ministry announced.
There was no evidence of any harm to civilians in the attack on Saturday evening and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
The Islamic State group - also known as Daesh - imposed jihadist rule over large swathes of both Syria and Iraq until 2019.
"This strike shows British leadership, and resolve to work closely with our allies, to stamp out any revival of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary John Healey remarked.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any efforts to regroup" of the group subsequent to its defeat at the battle of Baghuz in the year 2019, the MoD reported.
"I must thank the personnel of the UK armed forces involved in this strike for their expertise and their bravery," Healey said. "They were part of numerous British troops deployed over the festive period. This mission, to eliminate militants who pose a risk to our way of life, demonstrates how British military are prepared to act, continuously, protecting the UK at home and strong abroad."
Last December, the United States armed forces carried out what it called a "large-scale strike" on Islamic State objectives in Syria, following an attack killed two American soldiers and a civilian interpreter in the Palmyra area.
The UN estimates IS still has between 5,000 and 7,000 combatants in Syria and Iraq.
