A prominent jihadist commander was killed by a rival hardline group in northern Syria on Friday, a monitor said, in a new sign of fierce intra-rebel tensions in the area.
An array of rebel factions still hold parts of Aleppo province and almost all of neighbouring Idlib, but they have clashed several times in a struggle for influence.
Fighters from the Islamist Nureddine al-Zinki rebel group "fired on a car as it was crossing one of their checkpoints in the village of Al-Huta after midnight," the Syrian Observatory for Human Rights said.
