Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack against an underground arms cache in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountains just above the historic site of Palmyra in central Syria.
"The RAF jets used laser-guided Paveway IV weapons to hit a number of approach shafts down to the facility... initial indications indicate the objective was successfully hit," officials stated.
There was no sign of any harm to civilians in the attack on Saturday evening and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as the so-called Islamic State - imposed jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and determination to operate in unison with allied nations, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary remarked.
RAF aircraft have conducted patrols over Syrian airspace to "forestall any efforts to regroup" of Islamic State following its military defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I must thank the personnel of British forces participating in this mission for their skill and their courage," he said. "They were among numerous British personnel deployed over the holidays. This mission, to remove militants who endanger our way of life, demonstrates how British military are always on standby, throughout the year, ensuring Britain's security domestically and strong abroad."
During December, the US military conducted what it called a "massive strike" against Islamic State objectives in Syria, following an assault resulted in the deaths of two American soldiers and a civilian interpreter in Palmyra.
The UN reports IS still has an estimated 5,000 to 7,000 fighters in both countries.
