MOSCOW (AP) -- Separatists in eastern Ukraine on Tuesday proclaimed a new state that aspires to include not only the areas they control but also the rest of Ukraine.
The surprise announcement in the rebel stronghold of Donetsk casts further doubt on the 2015 cease-fire deal that was supposed to stop fighting in Ukraine's industrial heartland and bring those areas back into Kiev's fold while granting them wide autonomy. It also caught unawares some rebels who said they have no intention of joining the new state.
More than 10,000 people have died in fighting after Russia-backed rebels took control of parts of Ukraine's Donetsk and Luhansk regions in April 2014 after Russia annexed Ukraine's Crimean peninsula. The rebels originally sought to join Russia but the Kremlin stopped short of annexing the area or publicizing its military support for the rebels.
Donetsk separatist leader Alexander Zakharchenko said in comments broadcast on Russian television that rebels in Donetsk, Luhansk as well as representatives of other Ukrainian regions would form a state called Malorossiya.
Most of the areas which are currently part of Ukraine were referred to as Malorossiya, or Little Russia, when they were part of the Russian Empire.
Zakharchenko said they are drawing up a constitution that would be put up to a popular vote later.
"We believe that the Ukrainian state as it was cannot be restored," Zakharchenko said in remarks carried by the Tass news agency. "We, representatives of the regions of the former Ukraine, excluding Crimea, proclaim the creation of a new state which is a successor to Ukraine."
Although separatists in the east do have sympathizers in other Ukrainian regions, they have not attempted to capture territories there, nor do they have any political representation there.
Separatist leaders in Luhansk, however, later denied that they were part of the deal.
Local news website Luhansk Information Center quoted rebel representative Vladimir Degtyarenko as saying they had not been informed of the plans and have "great doubts about the expediency of such step."
Throughout the conflict, the rebel-controlled areas have been ruled by self-proclaimed authorities in Donetsk and Luhansk who call themselves the Donetsk People's Republic and the Luhansk People's Republic. Separatist leaders in Luhansk, unlike their counterparts in Donetsk, have tended to stay away from directly expressing intentions to join Russia.
France, Germany, Ukraine and Russia worked out an agreement in the Belarusian capital Minsk in 2015 which laid out a roadmap for ending the conflict between government troops and separatists. Under the deal, the rebels and the Ukrainian government agreed that the rebels would return the control of the territories they had captured to Kiev while Kiev would allow a local election there and grant wide autonomy to the region. While the deal helped to reduce the intensity of fighting, none of the political components have been implemented.
The Luhansk rebels insisted on Tuesday that they were committed to Minsk while Donetsk representatives argued that the creation of a new state does not contradict the deal.
Yevgen Marchuk, Ukraine's envoy at peace talks with the rebels, said on the 112 television channel on Tuesday that the announcement, made one day before the next round of talks in Minsk, "could block the negotiations entirely."
Kiev-based political analyst Volodymyr Fesenko speculated that the Kremlin had instigated the announcement, perhaps trying to scare the West with a possibility of Ukraine's breakup.
"The Kremlin is no longer trying to push this malignant tumor back into the body of Ukraine," Fesenko said, adding that it is too early to predict the fallout of Tuesday's announcement because Zakharchenko was known for making outlandish claims.
There was no immediate comment from Russia, which has been supporting the rebels. The Associated Press has documented how Moscow has been propping the separatists in Ukraine with funds, weapons and recruits. The Kremlin has firmly denied sending Russian troops to fight alongside the separatists despite the overwhelming evidence.
