A US drones strike has killed an IS group leader in Syria, officials claim.
It came after the three MQ-9 Reapers were harassed for two hours by Russian military jets over the western part of the country, Washington says.
The encounters happened when they were searching for the militant on Friday.
Shortly after, the drones struck and killed Usamah al-Muhajir, who was riding a motorcycle in the Aleppo region, said a US defence official.
It was not immediately clear how the US military confirmed the person killed was al-Muhajir.
US Central Command said in a statement yesterday there were no indications any civilians were killed in the strike.
Friday was the third day in a row that US officials complained Russian fighter jets in the region had made unsafe and harassing flights around drones.
A spokesman said the planes “flew 18 unprofessional close passes that caused the MQ-9s to react to avoid unsafe situations”.
