RAF Typhoon jets have conducted a mission with France's air force in a coordinated attack targeting an hidden munitions depot in Syria employed by the IS group, per a report from the British defence ministry.
The site, pinpointed through surveillance, was assessed as storing arms and explosives, the announcement noted, and was located in mountainous terrain just above Palmyra in Syria's central region.
"Our fighter planes employed precision-guided Paveway IV munitions to hit a several approach shafts down to the facility... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the attack conducted Saturday night and every plane involved returned to base without incident, the MoD added.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - imposed extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates our UK leadership, and commitment to operate in unison with our allies, to eradicate any re-emergence of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief John Healey stated.
British military aircraft have conducted patrols over Syrian airspace to "prevent any attempted resurgence" of Islamic State subsequent to its defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I extend gratitude to the personnel of our armed forces who took part in this operation for their professionalism and their courage," the Defence Secretary commented. "Including them were numerous British personnel deployed over the festive period. This operation, to take out terrorist threats who threaten our security, demonstrates how British military are prepared to act, continuously, keeping Britain secure domestically and influential overseas."
Last December, the US military executed what it termed a "major assault" on IS targets in Syria, following an ambush killed two US servicemembers and a civilian interpreter in the Palmyra area.
The U.N. says Daesh still has between 5,000 and 7,000 fighters in both countries.
