MOSCOW, October 20 (RIA Novosti) - Monday's heavy shelling of the eastern Ukrainian city of Donetsk undermines the negotiation process of the self-proclaimed Donetsk People's Republic (DPR) and Kiev, DPR Prime Minister Alexander Zakharchenko said.
"No more talks about ceasefire, of course we are not going to sit [at the negotiating table] with Kiev," he said.
There have been regular reports of the shelling of Donetsk ever since the Ukrainian forces and independence supporters of the eastern regions struck a ceasefire deal on September 5 in Minsk. The opposing sides have been trading blame for violating the ceasefire though the monitoring mission of the Organization for Security and Co-operation in Europe (OSCE) said the truce was generally holding.
The military confrontation in the east of Ukraine started in mid-April when the Kiev authorities sent troops to suppress the independence supporters in the eastern regions of the country.
On October 19, DPR Deputy Prime Minister Andrei Purgin said the self-proclaimed people's republic would never become part of a united Ukraine.
