Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a combined operation against an hidden munitions depot in Syrian territory operated by the Daesh militant organization, as stated by the UK's MoD.
The facility, identified by reconnaissance, was assessed as containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes employed precision-guided Paveway IV munitions to target a number of entry passages providing entry to the site... early reports indicate the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the operation conducted Saturday night and all the aircraft made a safe return, the MoD added.
The British jets were assisted by a Voyager tanker plane.
IS - alternatively referred to as Daesh - established extremist governance over significant areas in Syria and Iraq prior to its 2019 collapse.
"This operation shows our UK leadership, and determination to work closely with our allies, to eradicate any re-emergence of the terrorist group and their violent and radical beliefs in the area," the British Defence Secretary the minister remarked.
RAF aircraft have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of the group following its defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to every member of our armed forces who took part in this operation for their skill and their courage," he added. "They were part of numerous UK service members on duty over Christmas and New Year. This operation, to remove militants who threaten our safety, demonstrates how UK forces are prepared to act, all year round, ensuring Britain's security within its borders and influential overseas."
In December, the US military carried out what it termed a "major assault" against Daesh sites in Syria, after an assault claimed the lives of two US troops and a local interpreter in the Palmyra area.
The United Nations estimates Islamic State still boasts roughly 5-7 thousand combatants in Syria and Iraq.
