British Air Force Typhoon FGR4s have operated alongside French aircraft in a combined operation against an hidden munitions depot in Syria operated by the Daesh militant organization, per a report from the British defence ministry.
The facility, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to hit a series of approach shafts leading to the facility... early reports indicate the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the operation conducted Saturday night and every plane involved made a safe return, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as the so-called Islamic State - enforced extremist governance over large swathes of Iraq and Syria until 2019.
"This action demonstrates British leadership, and commitment to work closely with allied nations, to eliminate any re-emergence of IS and their dangerous and violent ideologies in the Middle East," UK Defence Secretary John Healey remarked.
RAF aircraft have performed overwatch operations over Syrian airspace to "deter any attempted comeback" of IS following its military defeat at the battle of Baghuz in the year 2019, the ministry said.
"I must thank the personnel of the UK armed forces participating in this operation for their skill and their courage," Healey said. "They were part of numerous UK service members deployed over the holidays. This operation, to remove terrorist threats who pose a risk to our safety, highlights how British military are always on standby, throughout the year, ensuring Britain's security domestically and strong abroad."
During December, the United States armed forces conducted what it described as a "major assault" on Daesh sites in Syria, after an ambush claimed the lives of two US troops and a civilian linguist in the Palmyra area.
The UN estimates Islamic State still maintains roughly 5-7 thousand militants in Syria and Iraq.
