(QHA) -

UN officials warned of a worsening humanitarian situation in eastern Ukraine as some UN Security Council members blamed Russia for the crisis.

John Ging, the director of UN humanitarian operations, said at the council's August 5 emergency meeting on the Ukrainian situation that fighting between Ukrainian forces and pro-Russian separatists is putting civilians at risk, especially in urban areas.

He said power and water supplies are becoming scarce because of the fighting and that more than 1,350 people -- civilians and combatants -- have been killed.

Russian UN Ambassador Vitaly Churkin said the situation in the cities of Luhansk and Donetsk is "disastrous" and said Russia wants to send a humanitarian convoy to the cities to help the civilian population.

But Security Council members Britain and the United States joined Ukraine in blaming Moscow's financial and material support for the separatists as the main reason for the crisis.
