Opposition leaders met in Munich on Friday with German Foreign Minister Frank-Walter Steinmeier and European Union foreign policy chief Catherine Ashton and were due to talk with U.S. Secretary of State John Kerry on Saturday.The Ukrainians were in the Bavarian capital to meet western officials at the annual Munich Security Conference.

"What we need is not just declarations but a very clear action plan - how to fix the problem and fix the violence, how to investigate all these killings and abductions and tortures," Arseniy Yatsenyuk, leader of the party of jailed former prime minister Yulia Tymoshenko declared, reports GHN according to Reuters.

"There is no one who can really steer the country," said Yatsenyuk, due to meet Kerry on Saturday with other opposition leaders including the boxer-turned-politician Vitaly Klitschko, lawmaker Petro Poroshenko and pop star Ruslana Lyzhychko.

Poroshenko said the amnesty and repeal of the anti-protest law "create a background for real negotiation" but what was most urgently needed was "de-escalation - we need to remove all the riot police from the streets of Kiev".

"We ask Russia for transparent relations," said opposition leader Yatsenyuk. "That is the key difference between our Western partners and the Russians: the West is open but Russia has a number of deals with the Ukrainian president and nobody knows the details of these deals."
