VIENNA, September 02. /ITAR-TASS/. The city of Luhansk in eastern Ukraine is left without water and electricity supplies and only one hospital appears to be operational, the OSCE (Organization for Cooperation and Security in Europe) monitoring mission said on Tuesday.

"Drinking water was distributed in cisterns," the Special Monitoring Mission (SMM) said in its daily report on the situation in Ukraine.

Ukrainian emergency officials told the OSCE mission that only 250,000 people remained in Luhansk, compared to 420,000 people who lived in the city before the conflict, the SMM reported.

"The interlocutors expressed concern that Luhansk could face a potential humanitarian catastrophe because shelling had damaged the city’s water supply system. If the problem would not be addressed within a couple of weeks, he said, the water reservoir could be contaminated," the SMM said.
