The scale of the destruction in the besieged Ukrainian city of Mariupol has been revealed in a series of photos and satellite images.
Residential areas have been flattened, a shopping centre destroyed and a maternity hospital attacked. The southern port city has used at least one mass grave to bury the dead.
Mariupol, a city of about 400,000, has been subjected to days of heavy bombardment.
Its people are running dangerously short of food and water, the city's deputy mayor Sergei Orlov, says, and there is "no electricity, no water supply, no heating, no sanitary system".
People are being forced to melt snow to drink, and chop wood to cook and keep warm in sub-zero temperatures, he says.
