British Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation on an hidden munitions depot in Syria employed by the IS group, per a report from the British defence ministry.
The location, identified by intelligence, was assessed as containing munitions and bombs, the release indicated, and was located in mountainous terrain just above the ancient city of Palmyra in central Syria.
"Our aircraft employed Paveway IV guided bombs to strike a number of entry passages leading to the depot... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian casualties in the operation on Saturday evening and all the aircraft returned safely, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - alternatively referred to as ISIS - enforced militant control over parts of both Syria and Iraq until 2019.
"This action demonstrates British leadership, and resolve to stand shoulder to shoulder with our partners, to eliminate any re-emergence of IS and their violent and radical beliefs in the area," the British Defence Secretary John Healey stated.
UK warplanes have carried out patrols over Syria to "forestall any attempted comeback" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank the personnel of the UK armed forces who took part in this operation for their skill and their valour," Healey said. "They were among numerous British troops on duty over the festive period. This operation, to eliminate dangerous terrorists who endanger our security, demonstrates how British military are ready to step up, continuously, protecting the UK at home and influential overseas."
During December, the US military carried out what it termed a "large-scale strike" on Daesh sites in Syria, after an assault killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN estimates Daesh still boasts between 5,000 and 7,000 militants in Syria and Iraq.
