British Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a combined operation on an hidden munitions depot in Syria employed by the IS group, as stated by the UK's MoD.
The location, pinpointed through surveillance, was assessed as containing munitions and bombs, the release indicated, and was located in mountainous terrain just above the historic site of Palmyra in the heart of Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to hit a number of entry passages down to the facility... early reports suggest the strike was effective," the ministry announced.
There was no indication of any civilian impact in the attack on Saturday evening and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - established jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to eradicate any resurgence of the terrorist group and their dangerous and violent ideologies in the area," Britain's Defence Chief the minister said.
RAF aircraft have performed patrols over Syria to "prevent any efforts to regroup" of IS after its defeat at the battle of Baghuz in 2019, the MoD reported.
"I want to thank the personnel of British forces involved in this mission for their professionalism and their bravery," he added. "They were part of numerous UK service members stationed over Christmas and New Year. This action, to take out terrorist threats who threaten our safety, shows how UK forces are always on standby, throughout the year, protecting the UK at home and strong abroad."
Last December, the United States armed forces conducted what it described as a "major assault" on Daesh sites in the country, after an assault killed two US troops and a civilian interpreter in Palmyra.
The United Nations says Daesh still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
