RAF Typhoon FGR4s have conducted a mission with French warplanes in a joint strike on an subterranean weapons facility in Syria employed by the IS group, as stated by the British defence ministry.

There was no evidence of any harm to civilians in the operation on Saturday evening and each participating jet returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
