British Air Force Typhoon jets have operated alongside French aircraft in a joint strike against an underground arms cache in Syrian territory operated by the Daesh militant organization, per a report from the British defence ministry.
The site, pinpointed through reconnaissance, was thought to be containing munitions and bombs, the release indicated, and was located in mountains just north of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to hit a number of approach shafts providing entry to the site... preliminary assessments indicate the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the strike conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager refuelling tanker.
IS - referred to as the so-called Islamic State - established extremist governance over parts of Iraq and Syria until 2019.
"This action shows British leadership, and resolve to work closely with our allies, to eradicate any revival of IS and their violent and radical beliefs in the Middle East," Britain's Defence Chief the minister stated.
UK warplanes have carried out patrols over Syria to "deter any efforts to regroup" of IS following its defeat at the battle of Baghuz in 2019, the authorities noted.
"I want to thank every member of British forces involved in this mission for their professionalism and their courage," he said. "Including them were numerous British personnel on duty over the festive period. This mission, to take out militants who pose a risk to our security, highlights how UK forces are prepared to act, continuously, keeping Britain secure within its borders and strong abroad."
In December, the US military conducted what it termed a "massive strike" on IS targets in the country, following an assault claimed the lives of two US servicemembers and a civilian interpreter in the Palmyra area.
The U.N. estimates Daesh still has roughly 5-7 thousand militants in Iraq and Syria.
