US drone strike kills Islamic State group leader in Syria, says official
A US drone strike killed a leader of so-called Islamic State (IS) in Syria hours after the same MQ-9 Reaper drones were harassed by Russian military jets over the western part of the country, according to US officials.
Three Reapers had been flying overhead searching for the militant on Friday, a US defence department official said, when they were harassed for about two hours by Russian aircraft.
