2 Ukraine regions set to vote on sovereignty as president warns of 'a step into the abyss'

Pro-Russian insurgents in two of the most tense regions in eastern Ukraine were prepared to conduct a vote Sunday on declaring sovereignty, while the country's acting president warned that it represented "a step into the abyss."

The ballots seek approval for declaring so-called sovereign people's republics in the Donetsk and Luhansk regions, where the insurgents have seized government buildings and clashed with police and Ukrainian troops.

The referendums are not regarded as legitimate by Kiev or the West.

"The United States will not recognize the results of these illegal referenda," State Department spokesperson Jen Psaki said in a statement late Saturday, calling the votes "an attempt to create further division and disorder."

The hastily arranged referendums are similar to the March referendum in Crimea that approved secession from Ukraine. Crimea was formally annexed by Russia days later.

But organizers of Sunday's vote have said that only later will a decision be made on whether they would use their nominal sovereignty to seek full independence, absorption by Russia or to stay part of Ukraine but with expanded power for the regions.

Ukrainian President Oleksandr Turchynov, in comments posted on the presidential website Saturday, said supporters of independence for the east "don't understand that this would be a complete destruction of the economy, social programs and general life for the majority of the population."

"This is a step into the abyss for the regions," he said.

The elections chief of the insurgents in Donetsk, Roman Lyagin, was quoted by news agencies as saying voting in Mariupol and one other district had begun early because of rising tensions there. He did not elaborate.

At least seven people died Friday in clashes in Mariupol. The city remained on edge Saturday, with barricades of tires blocking some streets in the city center.

Turchynov and Ukraine's interim government came to power in February following the ouster of Russia-friendly president Viktor Yanukovych after months of protests in Kiev. Moscow and many in Ukraine's east denounce the government as a nationalist junta and allege that it intends to trample on the rights of eastern Ukraine's Russian-speakers.

More than 30 people have been reported killed as Ukrainian forces mount offensives to retake some eastern cities now under control of the insurgents.

In the remarks issued Saturday, Turchynov said the government was willing to negotiate with representatives of the east, but not with anyone he called "terrorists whose task is the destruction of the country, a task put forth by their masters."

Kiev claims Russia is fomenting or directing the unrest in the east, with the goal of destabilizing Ukraine or finding a pretext for invasion.
