BEIRUT — Syria's state media said Monday that government troops repulsed a rebel attack on a police school in the northern city of Aleppo, one day after President Bashar Assad called on Syrians to fight an opposition that he characterized as religious extremists.

SANA news agency said members of the "terrorist group" were killed and wounded in the late Sunday battle but did not specify the number. The government and the pro-regime media refer to rebels as terrorists.

Aleppo, Syria's largest city and a former commercial hub, has been a major front in the civil war since July, with battles often raging for control of military and security facilities such as the police school. Rebels have recently made significant advances there, in the east, and in the capital Damascus, bringing the civil war closer to the seat of Assad's power.
