John Ging, director of U.N. humanitarian operations, said that violence, especially in urban areas, will put more people at risk and lead to "an increase in the numbers killed" if a political solution can't be reached, Censor.NET reports citing AP.
"Immediate action is therefore required to prevent this," he told council members. To date, 1,367 people, civilians and combatants, have been killed, Ging said.
Ukraine's deputy ambassador Oleksandr Pavlichenko denied there was a humanitarian crisis in Ukraine but said the humanitarian situation in Donetsk and Luhansk is still serious. "The situation is manageable by the government of Ukraine, which remains open to cooperation with international partners," he said.

Ging said nearly 4 million people living in the region are affected by violence. Water and power supplies have sustained significant damage.
In Donetsk and Luhansk, the water supply has been cut to a few hours per day, health supplies are running low and an estimated 70 percent of health personnel have fled, he said.

Just over 4,000 people have been wounded in eastern Ukraine since April. About 58,000 people have left since early July, and more than a thousand others are fleeing each day, Ging said.
Fighting across eastern Ukraine has forced more than 285,000 people to flee their homes, according to U.N. figures released Tuesday. The U.N. refugee agency said more than 117,000 have left for other places inside Ukraine, while another 168,000 have crossed into Russia.
