Royal Air Force Typhoon jets have joined forces with French aircraft in a joint strike on an underground arms cache in Syrian territory operated by the Daesh militant organization, as stated by the British defence ministry.
The site, located using intelligence, was assessed as containing munitions and bombs, the announcement noted, and was situated in hills just above the historic site of Palmyra in the heart of Syria.
"Our aircraft used Paveway IV guided bombs to strike a series of entry passages leading to the facility... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no evidence of any civilian impact in the attack on Saturday evening and every plane involved made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - established extremist governance over large swathes of Syria and Iraq until 2019.
"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our allies, to eradicate any resurgence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have carried out patrols over Syrian airspace to "deter any attempted comeback" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of our armed forces involved in this mission for their professionalism and their courage," Healey added. "They were part of thousands of UK service members stationed over the festive period. This operation, to take out dangerous terrorists who endanger our security, demonstrates how our armed forces are ready to step up, all year round, protecting the UK domestically and influential overseas."
During December, the United States armed forces conducted what it called a "large-scale strike" against Islamic State objectives in Syria, after an ambush claimed the lives of two US servicemembers and a civilian linguist in the Palmyra area.
The UN reports Daesh still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
