British Air Force Typhoon fighter aircraft have conducted a mission with French aircraft in a combined operation against an hidden munitions depot in Syria used by the IS group, according to the British defence ministry.
The site, identified by reconnaissance, was assessed as storing arms and explosives, the release indicated, and was positioned in mountainous terrain just above Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to hit a several access tunnels providing entry to the facility... preliminary assessments indicate the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the strike late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager tanker plane.
IS - alternatively referred to as ISIS - established extremist governance over parts of Iraq and Syria until 2019.
"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our partners, to stamp out any revival of IS and their harmful and extremist ideologies in the area," UK Defence Secretary the minister remarked.
UK warplanes have performed surveillance missions over Syrian airspace to "deter any attempted comeback" of IS after its routing at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to all the members of the UK armed forces involved in this mission for their expertise and their valour," Healey said. "They were part of thousands of UK service members stationed over Christmas and New Year. This mission, to take out dangerous terrorists who threaten our way of life, shows how UK forces are always on standby, all year round, ensuring Britain's security domestically and influential overseas."
In December, the United States armed forces carried out what it termed a "massive strike" on Daesh sites in Syria, subsequent to an assault resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The UN says Islamic State still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
