RAF Typhoon jets have operated alongside France's air force in a combined operation on an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, located using surveillance, was thought to be storing arms and explosives, the release indicated, and was situated in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our aircraft used laser-guided Paveway IV weapons to target a several entry passages down to the site... early reports indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the operation conducted Saturday night and every plane involved returned safely, the MoD added.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - enforced jihadist rule over large swathes of Syria and Iraq until 2019.
"This action demonstrates the UK's leading role, and resolve to stand shoulder to shoulder with our allies, to eradicate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," 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 following its routing at the battle of Baghuz in the year 2019, the MoD reported.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their skill and their valour," he added. "They were part of numerous UK service members deployed over the festive period. This action, to take out militants who threaten our security, demonstrates how our armed forces are ready to step up, continuously, protecting the UK within its borders and powerful internationally."
During December, the United States armed forces carried out what it described as a "massive strike" targeting IS targets in the country, after an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The U.N. says IS still maintains between 5,000 and 7,000 militants in Iraq and Syria.
