Activists and local residents say intense clashes between a Western-backed rebel group and al-Qaeda's Syrian affiliate have killed at least 20 fighters on the outskirts of the northern city of Aleppo.
The Britain-based Syrian Observatory for Human Rights says fighters from the al-Qaeda-linked Nusra Front battled members of the mainstream Hazm Movement late Friday and early Saturday. It says Nusra fighters overran several Hazm bases near the town of Atarib.
