RAF Typhoon FGR4s have joined forces with French aircraft in a joint strike targeting an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), according to the UK Ministry of Defence.
The facility, pinpointed through surveillance, was assessed as storing arms and explosives, the announcement noted, and was situated in hills just to the north of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to target a several access tunnels providing entry to the facility... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no evidence of any civilian casualties in the attack on Saturday evening and all the aircraft returned safely, the MoD added.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
IS - also known as the so-called Islamic State - imposed extremist governance over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation shows the UK's leading role, and determination to stand shoulder to shoulder with our partners, to stamp out any revival of IS and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary stated.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any attempted comeback" of Islamic State after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of British forces who took part in this operation for their professionalism and their courage," he said. "They were part of a great many British personnel stationed over Christmas and New Year. This action, to eliminate militants who pose a risk to our way of life, demonstrates how our armed forces are prepared to act, continuously, keeping Britain secure domestically and strong abroad."
During December, the American forces conducted what it described as a "massive strike" targeting Islamic State objectives in the country, subsequent to an ambush killed two American soldiers and a civilian interpreter in Palmyra.
The UN estimates Islamic State still boasts roughly 5-7 thousand combatants in Syria and Iraq.
