Royal Air Force Typhoon fighter aircraft have conducted a mission with French aircraft in a combined operation on an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), as stated by the UK's MoD.
The facility, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in mountainous terrain just north of Palmyra in central Syria.
"Our aircraft used laser-guided Paveway IV weapons to hit a series of approach shafts providing entry to the depot... initial indications suggest the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the operation on Saturday evening and each participating jet returned safely, the MoD added.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - referred to as ISIS - established militant control over parts of Syria and Iraq prior to its 2019 collapse.
"This operation underscores the UK's leading role, and commitment to work closely with our allies, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary John Healey stated.
British military aircraft have conducted overwatch operations over Syrian airspace to "deter any attempted comeback" of the group after its routing at the climactic battle in Baghuz in the year 2019, the ministry said.
"I extend gratitude to every member of our armed forces participating in this strike for their skill and their courage," the Defence Secretary commented. "They were part of thousands of British personnel on duty over the festive period. This mission, to remove militants who endanger our safety, highlights how British military are ready to step up, continuously, protecting the UK domestically and strong abroad."
Last December, the US military executed what it termed a "major assault" targeting IS targets in Syria, following an ambush resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The United Nations says Daesh still maintains an estimated 5,000 to 7,000 fighters in Iraq and Syria.
