Ukraine 'evacuated buildings with tear gas' in Mariupol
Russia's President Vladimir Putin has called for dialogue to resolve the crisis in Ukraine, and called on anti-government activists in the country's largely Russian-speaking east to postpone a vote on independence.
But across the region, key official buildings are still occupied by pro-Russian groups.
Police briefly dislodged the activists on Wednesday morning in the city of Mariupol - but now they are back and insist they still want the right to vote on breaking away from Kiev.
