Activist groups puts death toll in 2-week assault on Syria's Aleppo at more than 500

A Syrian activist group says more than 500 people have been killed in the government's two-week aerial assault on opposition-held areas of the northern city of Aleppo and its suburbs.

President Bashar Assad's aircraft have pummeled rebel areas of the divided city since Dec. 15, often with crude barrel bombs that cause massive damage upon impact.

The Britain-based Syrian Observatory for Human Rights said Sunday the aerial campaign killed at least 517 people, including 151 children and 46 women, as of midnight Saturday.

The Observatory monitors the conflict through a network of activists on the ground.

The Syrian government hasn't commented on the campaign.
