Amnesty International has released satellite images that it says show the use of heavy weaponry close to civilian areas in and around the Syrian city of Aleppo.
In the image above, each yellow dot represents a probable artillery impact crater in Anadan close to Aleppo. There are more than 600 of them.
The image below is a close-up of a residential housing complex near Anadan. The craters are clearly visible.
Press reports indicate that food and basic supplies, including cooking gas and fuel for vehicles, are in short supply in Aleppo. This final image shows a long queue of vehicles outside a petrol station near the centre of Aleppo.
Amnesty International says the pictures indicate the "increased use of heavy weaponry" near civilian areas, and warns that both sides in the conflict could be held criminally responsible. Read its full statement here.
