Ukraine announces start of anti-terrorist operation in Donetsk
Acting Ukrainian President Oleksandr Turchynov says an "anti-terrorist operation" has started in the eastern region of the country.
Addressing parliament, Turchynov has provided few details of the operation, saying only that it will be conducted with "caution and responsibility".
"Today in the morning an anti-terrorist operation has started in the east of Donetsk region. But it will be carried out stage by stage, responsibly and cautiously. The aim of these actions - I underline it one more time - is to protect the citizens of Ukraine, to stop terror, and to stop criminality, stop attempts to tear Ukraine to pieces."
The announcement comes as pro-Russia protestors continue occupying government buildings in over 10 cities and towns in the eastern regions of Ukraine.
Ukranian authorities gave pro-Russian protesters until yesterday to disarm, or face what he called, a "full-scale anti-terrorist operation".
Meanwhile, U.S. President Barack Obama and Russian President Vladimir Putin have been expressing sharply different views on the current unrest in eastern Ukraine, but both urging the other side to help bring the situation to an end.
The two leaders have spoken via the phone, at Moscow's request.
Obama is said to have expressed "grave concern" about Russia's apparent support for the actions of pro-Russia armed groups.
Putin has denied that Moscow is interfering in Ukraine.
He's called on the US side to use its influence to prevent more bloodshed in Ukraine.
At the same time, the European Union has agreed to expand its sanctions against Russia following recent developments in the east of Ukraine.
The new sanctions will put more people under an asset freeze and visa bans.
