British Air Force Typhoon fighter aircraft have operated alongside French aircraft in a coordinated attack on an underground arms cache in Syrian territory operated by the IS group, as stated by the UK Ministry of Defence.
The location, located using intelligence, was thought to be containing munitions and bombs, the announcement noted, and was positioned in mountainous terrain just above Palmyra in central Syria.
"Our aircraft employed precision-guided Paveway IV munitions to target a series of access tunnels down to the depot... early reports suggest the strike was effective," the MoD said.
There was no indication of any harm to civilians in the operation on Saturday evening and every plane involved returned safely, the MoD added.
The British jets were supported by a Voyager tanker plane.
The Islamic State group - alternatively referred to as the so-called Islamic State - imposed militant control over large swathes of Iraq and Syria until 2019.
"This action demonstrates British leadership, and commitment to stand shoulder to shoulder with our partners, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary stated.
UK warplanes have performed patrols over Syrian airspace to "deter any attempted comeback" of Islamic State after its routing at the Baghuz confrontation in 2019, the authorities noted.
"I must thank every member of our armed forces participating in this operation for their skill and their valour," the Defence Secretary commented. "Including them were a great many British troops on duty over the holidays. This mission, to eliminate militants who pose a risk to our safety, shows how UK forces are ready to step up, continuously, protecting the UK within its borders and powerful internationally."
In December, the US military executed what it termed a "massive strike" on Daesh sites in Syria, subsequent to an ambush resulted in the deaths of two US troops and a local interpreter in the Palmyra area.
The United Nations says IS still boasts between 5,000 and 7,000 militants in both countries.
