Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a joint strike targeting an hidden munitions depot in Syria employed by the Islamic State group (IS), per a report from the UK's MoD.
The location, pinpointed through surveillance, was believed to be storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just to the north of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to hit a number of entry passages leading to the site... early reports suggest the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon FGR4s were supported by a Voyager tanker plane.
The Islamic State group - referred to as Daesh - enforced militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This strike demonstrates British leadership, and commitment to work closely with allied nations, to stamp out any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the minister stated.
British military aircraft have conducted overwatch operations over Syria to "prevent any attempted comeback" of the group following its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces who took part in this operation for their expertise and their courage," he commented. "They were part of a great many UK service members stationed over the holidays. This mission, to eliminate militants who pose a risk to our safety, highlights how our armed forces are ready to step up, continuously, keeping Britain secure at home and influential overseas."
During December, the United States armed forces carried out what it described as a "massive strike" targeting IS targets in the country, after an attack resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The United Nations reports Islamic State still has between 5,000 and 7,000 fighters in both countries.
