Royal Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack against an underground arms cache in Syria used by the Daesh militant organization, as stated by the UK's MoD.
The facility, identified by intelligence, was believed to be storing arms and explosives, the statement said, and was positioned in mountains just above Palmyra in Syria's central region.
"Our fighter planes used Paveway IV guided bombs to hit a several entry passages leading to the site... early reports indicate the objective was successfully hit," officials stated.
There was no sign of any harm to civilians in the attack on Saturday evening and every plane involved returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager tanker plane.
The Islamic State group - also known as Daesh - established militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action shows British leadership, and commitment to work closely with our partners, to eliminate any revival of Daesh and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister stated.
UK warplanes have carried out patrols over Syrian airspace to "deter any attempted resurgence" of the group after its defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank all the members of the UK armed forces involved in this operation for their professionalism and their bravery," the Defence Secretary said. "They were among a great many British personnel deployed over Christmas and New Year. This mission, to take out dangerous terrorists who threaten our way of life, demonstrates how UK forces are prepared to act, continuously, keeping Britain secure at home and influential overseas."
Last December, the American forces executed what it called a "major assault" against IS targets in Syria, after an attack resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations estimates Daesh still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
