RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a coordinated attack targeting an hidden munitions depot in Syria employed by the IS group, according to the British defence ministry.
The location, pinpointed through intelligence, was assessed as containing munitions and bombs, the release indicated, and was situated in hills just above the ancient city of Palmyra in central Syria.
"The RAF jets employed laser-guided Paveway IV weapons to strike a several access tunnels leading to the depot... initial indications are that the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the attack on Saturday evening and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
IS - also known as ISIS - imposed extremist governance over significant areas in both Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and determination to stand shoulder to shoulder with our partners, to stamp out any resurgence of the terrorist group and their harmful and extremist ideologies in the region," UK Defence Secretary John Healey said.
RAF aircraft have conducted overwatch operations over Syrian airspace to "prevent any efforts to regroup" of Islamic State following its defeat at the battle of Baghuz in the year 2019, the MoD reported.
"I want to thank all the members of British forces who took part in this mission for their skill and their courage," the Defence Secretary commented. "They were among a great many British troops deployed over the festive period. This operation, to eliminate militants who endanger our way of life, demonstrates how our armed forces are ready to step up, throughout the year, protecting the UK at home and strong abroad."
In December, the US military executed what it termed a "massive strike" targeting Islamic State objectives in Syria, following an ambush resulted in the deaths of two US troops and a civilian linguist in the Palmyra area.
The United Nations estimates Daesh still boasts an estimated 5,000 to 7,000 combatants in Syria and Iraq.
