British Air Force Typhoon fighter aircraft have conducted a mission with French aircraft in a joint strike on an subterranean weapons facility in Syria employed by the Daesh militant organization, per a report from the British defence ministry.
The site, located using reconnaissance, was believed to be storing arms and explosives, the statement said, and was situated in mountainous terrain just above Palmyra in Syria's central region.
"The RAF jets used Paveway IV guided bombs to target a series of approach shafts down to the depot... preliminary assessments indicate the strike was effective," the ministry announced.
There was no indication of any harm to civilians in the strike on Saturday evening and every plane involved returned to base without incident, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
