Moscow has attacked Ukraine’s interim leaders for using “terrorist tactics” to silence pro-Russian supporters.
Prime Minister Dmitry Medvedev has voiced grave doubts over the legitimacy of the authorities following the removal of Viktor Yanukovych.
In a strongly worded statement, he made clear he was not ready to engage with anyone he said who came to power in an “armed mutiny”.
“There is no government. There are big doubts about the legitimacy of a whole series of organs of power that are now functioning there,” said Medvedev.
“Some of our Western partners think differently. They think it is a legitimate body. I do not know what Constitution they are reading,” he added.
Medvedev also reportedly believes Russian citizens and interests are under threat which is why Russia recalled its Kyiv ambassador Mikhail Zurabov on Sunday night.
Meanwhile, the EU’s foreign policy chief Catherine Ashton has arrived in Ukraine to discuss fresh measures to shore up its ailing economy.
It is understood an international donors’ conference is on the agenda as Ukraine’s finance ministry says it needs urgent help to avoid default.
