Royal Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack on an subterranean weapons facility in Syria employed by the Daesh militant organization, per a report from the UK's MoD.
The facility, identified by reconnaissance, was assessed as containing munitions and bombs, the release indicated, and was positioned in mountains just to the north of Palmyra in central Syria.
"The RAF jets employed Paveway IV guided bombs to target a number of entry passages providing entry to the depot... initial indications are that the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike on Saturday evening and every plane involved returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - referred to as Daesh - imposed jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action shows our UK leadership, and commitment to operate in unison with our partners, to stamp out any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the minister stated.
British military aircraft have performed patrols over Syrian airspace to "deter any efforts to regroup" of the group after its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to all the members of the UK armed forces involved in this mission for their skill and their valour," Healey added. "They were part of numerous British troops deployed over Christmas and New Year. This mission, to eliminate dangerous terrorists who pose a risk to our safety, highlights how UK forces are ready to step up, continuously, protecting the UK within its borders and strong abroad."
In December, the United States armed forces executed what it called a "major assault" targeting Daesh sites in Syria, following an ambush claimed the lives of two US troops and a civilian linguist in the Palmyra area.
The United Nations says Daesh still boasts roughly 5-7 thousand combatants in Iraq and Syria.
