Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a coordinated attack against an hidden munitions depot in Syria used by the IS group, as stated by the UK's MoD.
The location, pinpointed through reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was positioned in mountains just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes used precision-guided Paveway IV munitions to strike a series of access tunnels providing entry to the site... early reports indicate the objective was successfully hit," the ministry announced.
There was no indication of any civilian impact in the operation late on Saturday and each participating jet returned safely, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - also known as ISIS - established jihadist rule over parts of both Syria and Iraq until 2019.
"This action underscores British leadership, and resolve to operate in unison with our partners, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary John Healey stated.
RAF aircraft have performed overwatch operations over Syria to "deter any efforts to regroup" of Islamic State after its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to the personnel of the UK armed forces involved in this mission for their professionalism and their valour," the Defence Secretary said. "They were among thousands of British troops deployed over the holidays. This action, to eliminate dangerous terrorists who threaten our safety, demonstrates how our armed forces are prepared to act, all year round, protecting the UK within its borders and powerful internationally."
In December, the American forces carried out what it described as a "massive strike" against Islamic State objectives in Syria, subsequent to an attack claimed the lives of two US servicemembers and a civilian linguist in the Palmyra area.
The UN reports IS still maintains an estimated 5,000 to 7,000 combatants in both countries.
