SLOVIANSK, June 03. /ITAR-TASS/. People’s militia in the conflict-hit south-eastern Ukrainian city of Sloviansk downed a Su-25 fighter and a combat helicopter as well as destroyed four armoured combat vehicles as pro-Kiev troops continue attacks on the city, Sloviansk People’s Mayor Vyacheslav Ponomarev said on Tuesday.

Ponomarev said that on Tuesday two militia people were killed in armed clashes near Sloviansk, adding that “there were no casualties reported among civilians.”

His spokeswoman Stella Khorosheva said that Ukraine's military has amassed armoured vehicles and self-propelled mortars and howitzers near the city. The military equipment numbering 100 units includes Grad salvo systems.

At the Ukrainian parliament’s session on Tuesday, Vladimir Medyanik, a lawmaker with the Communist Party, urged the government to immediately stop the bloodshed in the eight-million populated south-eastern region of Ukraine, where the death toll already amounts to dozens or hundreds killed.

He also said that a Ukrainian warplane killed seven people and wounded ten in a missile strike at the Luhansk regional administrative building on Monday night.

“Hostilities should be stopped immediately. There cannot be a winner in the civil war,” Medyanik said addressing the parliament.

Ukraine's parliament-appointed acting prosecutor general said 181 people were dead and 293 wounded since fighting broke out in the country's eastern Donetsk and Luhansk regions.

"Fifty-nine servicemen were among those killed," Oleg Makhnitsky told a news conference on Tuesday, adding that more than 200 people, including 12 foreigners, had been abducted in the country's east.

Prosecutors had opened 765 criminal cases over sabotage, terrorist attacks and riots, he said.

Massive protests against the coup-imposed Ukrainian authorities erupted in Ukraine’s south-eastern territories, mainly the Donetsk and Luhansk regions, after Crimea’s merger with Russia. Demonstrators in the Southeast, who have been demanding Ukraine’s federalization, seized some government buildings.

A punitive operation by Kiev against federalization supporters has already claimed dozens of lives, including civilian. The Donetsk and Luhansk regions held referendums on May 11, in which most voters supported independence from Ukraine.

People’s Mayor of Donetsk Alexander Lukyanchenko said evacuation of all people from his city is impossible at the moment. He said there are currently 60,000 children and about 270,000 elderly staying in the city.
