And turning to the deepening crisis in Ukraine.
Ukrainian Prime Minister Arseny Yatseniuk says that Russia is exporting terrorism to the country, calling it an international crime.
Addressing his cabinet, Yatseniuk said that Russian special forces were infiltrating Ukrainian territory and committing acts of terrorism.
His remarks come on the eve of four-way talks in Geneva between diplomats from Russia, the EU, the U.S. and Ukraine.
Earlier Wednesday, Ukrainian armed forces had lost control of six armored personnel carriers to pro-Russian militants in the eastern city of Slaviansk.
Other separatist groups have also reportedly taken over the mayor's office in the city of Donestsk, as Kiev continues to lose its grip of eastern regions.
The Ukrainian government launched an anti-terrorism operation on Tuesday against the armed pro-Russian groups, retaking a military airfield in the town of Kram-a-torsk.
Russia's President Vladimir Putin has condemned Kiev for the latest military operation, saying Ukraine is on the brink of civil war.
Meanwhile South Korea's foreign ministry issued a travel advisory advising citizens to avoid eastern Ukraine.
