Syria crisis: Amnesty alarm at Aleppo 'bombing' images
Satellite images show increased use of heavy weapons in Aleppo, raising urgent concerns over the welfare of Syrian civilians, Amnesty International says.
The rights group says the photos reveal more than 600 craters, which were probably caused by artillery shells.
Both government troops and rebels may be held criminally responsible for failing to protect civilians, it warns.
