Syria troops shell Aleppo neighborhoods

Aleppo-based activist Mohammed Saeed says the shelling is most intense in the southwestern neighborhoods of Salaheddine and Saif al-Dawla, some of the first areas seized by the opposition fighters when they started last week a push to take over the city after being routed from the capital Damascus.

The Britain-based Syrian Observatory for Human Rights also reported heavy fighting and explosions in Aleppo Sunday.

The government said security agents were hunting down armed groups in Salaheddine.
