Kiev forces have shelled residential areas in the center of the rebel-held town of Donetsk, killing at least three people and damaging several apartment blocks, a kindergarten and a cultural center.
On Wednesday, Kalininsky District in the center of the city came under artillery fire from the government forces.
One of the missiles directly hit a passenger car on Shevchenko Boulevard, turning the vehicle into a torch.
“There’s a car where three people have died and the bodies are badly burned inside,” Slier said.
Ukraine has been engulfed in a violent internal conflict since April, when Kiev’s military began its crackdown on the southeast parts of the country.
Some of the people in the Donetsk and Lugansk regions refused to recognize the new coup-imposed authorities and demanded federalization of the country.
According to United Nations’ estimates released Tuesday, over 2,249 people have so far been killed and over 6,033 wounded in the fighting in eastern Ukraine.
The number of internally displaced Ukrainians has reached 190,000, with another 207,000 finding refuge in Russia, the UN said.
