Western-backed Syrian rebels say kill foreign Islamic State fighters in undercover strike

AMMAN (Reuters) - A group of Western-backed Syrian insurgents said on Tuesday they had killed three foreign fighters -- two Saudis and a Tunisian -- with the Islamic State group in an undercover raid into an area under the control of the ultra-radical militants.

An alliance of rebel groups known as Jabhat al Shamiya (Levant Front) operating in the northern Aleppo countryside near the border with Turkey said the operation was conducted by their clandestine security unit and was the first of its kind.
