Pro-Moscow protesters in Eastern Ukraine seized arms in one city and declared a separatist republic in another, in moves Kiev described yesterday as part of a Russian-orchestrated plan to justify an invasion to dismember the country.

Kiev said the overnight seizure of public buildings in three cities in Eastern Ukraine’s mainly Russian-speaking industrial heartland were a replay of the events which occurred in Crimea, the Black Sea peninsula Moscow seized and annexed last month.

“An anti-Ukrainian plan is being put into operation ... under which foreign troops will cross the border and seize the territory of the country,” Prime Minister Arseny Yatseniuk said in public remarks to his Cabinet. “We will not allow this.”

Pro-Russian protesters seized official buildings in the eastern cities of Kharkiv, Luhansk and Donetsk on Sunday night, demanding that referendums be held on whether to join Russia like the one that preceded Moscow’s takeover of Crimea.

Acting President Oleksander Turchinov, in a televised address to the nation, said Moscow was attempting to repeat “the Crimea scenario”. He added that “anti-terrorist measures” would be deployed against those who had taken up arms. Police said they cleared the protesters from the building in Kharkiv, but in Luhansk the demonstrators had seized weapons.

In Donetsk, home base of deposed Moscow-backed President Viktor Yanukovych, about 120 pro-Russia activists calling themselves the “Republican People’s Soviet of Donetsk” seized the chamber of the regional assembly.

An unidentified bearded man read out “the act of the proclamation of an independent state, Donetsk People’s Republic” in front of a white, blue and red Russian flag.

It is an attempt to destroy Ukrainian statehood, a script written in Russia

“In the event of aggressive action from the illegitimate Kiev authorities, we will appeal to the Russian Federation to bring in a peacekeeping contingent,” ran the proclamation. The activists later read out the text by loud hailer to a cheering crowd of about 1,000 outside the building.

Russian President Vladimir Putin announced on March 1, a week after Yanukovych was overthrown, that Moscow had the right to take military action in Ukraine to protect Russian speakers, creating the biggest confrontation between Moscow and the West since the Cold War.

The United States and EU imposed mild financial sanctions on some Russian officials over the seizure of Crimea and have threatened much tougher measures if Russian troops, now massed on the frontier, enter other parts of Ukraine.

Western European governments have hesitated to alienate Russia further, fearing for supplies of Russian natural gas, much of which reaches EU buyers via pipelines across Ukraine. Ukraine’s own dependence on Russian gas gives Moscow strong leverage, especially over Ukraine’s eastern indust-rial areas.

In Vienna, Russia did not attend a meeting on Ukraine of the Organisation for Security and Cooperation in Europe. The US envoy to the OSCE, Daniel Baer, said Moscow needed to explain why tens of thousands of its troops were massed on the border.

“It is an attempt to destroy Ukrainian statehood, a script which has been written in the Russian Federation, the aim of which is to divide and destroy Ukraine and turn part of Ukraine into a slave territory under the dictatorship of Russia,” Yatseniuk said.
