US diplomat calls for talks to resolve Ukraine crisis

The unrest in eastern Ukraine can only be solved through diplomacy, the U.S. ambassador to the Ukraine, Geoffrey Pyatt, told CNBC after the country's interior minister warned that force could be moved to remove pro-Russia separatists holding state buildings in at least two cities.

"There are two options—political and negotiations, and force," the minister Arsen Avakov told journalists on the margins of a government meeting.

"For those who want dialogue, we propose talks and a political solution. For the minority who want conflict they will get a forceful answer from the Ukrainian authorities," he said.

Pyatt told CNBC that a resolution to the turmoil could only come through negotiations, however he added that the balance of effort lied with Russian officials, who had "invented this crisis".

"I want to be clear: from where we sit, the action, the task ahead lies with Russia," Pyatt said on Wednesday in a television interview.

"They invented this crisis through their invasion of Crimea. They have now deepened the crisis through their stirring of unrest in eastern Ukraine, and they are the ones who will have to make a choice to deescalate."

Pyatt said there were strong signs the attacks in Ukrainian cities had been coordinated from outside the country.

"There is plenty of evidence that the simultaneous attacks on the government buildings in three or major eastern Ukrainian cities were not a coincidence. This was an orchestrated series of attacks, involving relatively small groups of violent individuals. There is evidence that they were paid from outside; there is evidence they were coordinating via radio," he said.
