Syrian troops kill 40 rebels in Aleppo

At least 40 rebels were killed Saturday by Syrian troops in the country's northern province of Aleppo, state media reported.

More than 40 "terrorists", most of whom are foreigners, were killed in a "special operation" carried out by the Syrian regular forces in Retyan village in the northern countryside of Aleppo, Xinhua reported citing SANA news agency.

The rebels have been losing their momentum recently as they have become plagued with infighting between those who showcase themselves as "moderate" rebels and the Islamic State of Iraq and the Levant (ISIL).

The Britain-based Syrian Observatory for Human Rights said Friday that the infighting that erupted between rebel groups in Syria have killed 500 people.

The battles started last Friday between various rebel groups and so-called Islamic State of Iraq and the Levant (ISIL), said the Observatory, adding that the toll includes 85 civilians, 240 rebels from various groups and 157 fighters from the ISIL.
