Royal Air Force Typhoon jets have joined forces with France's air force in a joint strike against an hidden munitions depot in Syria employed by the Daesh militant organization, according to the UK's MoD.
The facility, pinpointed through surveillance, was believed to be containing munitions and bombs, the announcement noted, and was located in hills just north of the historic site of Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to strike a several access tunnels providing entry to the facility... preliminary assessments are that the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the strike conducted Saturday night and all the aircraft returned to base without incident, the MoD added.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - established militant control over large swathes of both Syria and Iraq until 2019.
"This action underscores British leadership, and resolve to operate in unison with allied nations, to eradicate any revival of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief the minister stated.
RAF aircraft have conducted patrols over Syria to "prevent any attempted comeback" of Islamic State subsequent to its routing at the Baghuz confrontation in 2019, the ministry said.
"I extend gratitude to all the members of British forces involved in this mission for their skill and their courage," Healey added. "Including them were a great many British personnel on duty over the holidays. This mission, to eliminate militants who threaten our way of life, shows how British military are always on standby, continuously, keeping Britain secure at home and influential overseas."
In December, the US military conducted what it described as a "major assault" against Daesh sites in the country, following an assault killed two American soldiers and a civilian linguist in Palmyra.
The UN estimates Daesh still boasts between 5,000 and 7,000 militants in Syria and Iraq.
