Several thousand protesters took to the streets of Georgian capital Tbilisi for a fourth day on Sunday as tensions rose between Moscow and its ex-Soviet neighbour. Some protest placards took aim at Bidzina Ivanishvili, the oligarch leader of the ruling party, believed by many to be the power behind the scenes in the Western-backed country of 3.7 million people. Others slammed Russian President Vladimir Putin who in response to the protests has banned Russian airlines from flying to Georgia and Georgian air carriers travelling to Russia.
