At least 26 rebel fighters were killed Sunday by the Syrian troops in the northern province of Aleppo, a monitoring group said.
The killed rebels were from an array of jihadi groups, mainly the Al Qaeda-linked Nusra Front, Xinhua quoted the Syrian Observatory for Human Rights as saying.
It also added that the Syrian troops advanced Sunday in the northern part of Aleppo, capturing new areas.
Aleppo, once the economic hub of Syria, has seen the most ferocious battles between the rebels and the government troops.
