Reuters, Ukraine :
Germany’s Angela Merkel delivered a rebuke to President Vladimir Putin on Sunday, telling him that a planned Moscow-backed referendum on whether Crimea should join Russia was illegal and violated Ukraine’s constitution.
Putin defended breakaway moves by pro-Russian leaders in Crimea, where Russian forces tightened their grip on the Ukrainian Black Sea peninsula by seizing another border post and a military airfield.
As thousands staged rival rallies in Crimea, street violence flared in Sevastopol, when pro-Russian activists and Cossacks attacked a group of Ukrainians.
Chinese President Xi Jinping called for all parties to remain calm and urged a political solution to the crisis, during telephone calls with US President Barack Obama and Merkel.
“The situation in Ukraine is extremely complex, and what is most urgent is for all sides to remain calm and exercise restraint to avoid an escalation in tensions,” China’s foreign ministry on Monday cited Xi as telling Obama. “Political and diplomatic routes must be used to resolve the crisis,” Xi added.
Russian forces’ seizure of the region has been bloodless but tensions are mounting following the decision by pro-Russian groups there to make Crimea part of Russia.
In the latest armed action, pro-Russian forces wearing military uniforms bearing no designated markings sealed off a military airport in Crimea near the village of Saki, a Ukrainian Defence Ministry spokesman on the peninsula said.
The operation to seize Crimea began within days of Ukraine’s pro-Russian President Viktor Yanukovich’s flight from the country last month. Yanukovich was toppled after three months of demonstrations against a decision to spurn a free trade deal with the European Union for closer ties with Russia.
Ukrainian Prime Minister Arseny Yatseniuk will hold talks with President Barack Obama in Washington on Wednesday on how to find a peaceful resolution to the crisis, the White House said.
