Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike against an hidden munitions depot in Syrian territory operated by the Islamic State group (IS), as stated by the British defence ministry.
The location, pinpointed through surveillance, was believed to be containing munitions and bombs, the release indicated, and was located in mountains just above the historic site of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to strike a number of approach shafts leading to the depot... early reports indicate the target was engaged successfully," the MoD said.
There was no indication of any harm to civilians in the strike late on Saturday and all the aircraft returned to base without incident, the MoD added.
The British jets were supported by a Voyager refuelling tanker.
IS - alternatively referred to as Daesh - enforced jihadist rule over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This action demonstrates the UK's leading role, and resolve to operate in unison with our partners, to eradicate any re-emergence of IS and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed patrols over Syrian airspace to "forestall any attempted comeback" of the group after its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I extend gratitude to all the members of our armed forces participating in this mission for their professionalism and their courage," he commented. "They were part of numerous UK service members deployed over the holidays. This operation, to eliminate militants who threaten our security, shows how UK forces are prepared to act, continuously, ensuring Britain's security domestically and influential overseas."
Last December, the American forces carried out what it described as a "massive strike" against Islamic State objectives in the country, following an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN reports IS still has an estimated 5,000 to 7,000 combatants in Iraq and Syria.
