Russian President Vladimir Putin called on the Ukrainian military to seize power in their country on Friday, a day after Moscow launched an invasion of its southern neighbour. "I once again appeal to the military personnel of the armed forces of Ukraine: do not allow neo-Nazis and (Ukrainian radical nationalists) to use your children, wives and elders as human shields," Putin said at a televised meeting with Russia's security council. "Take power into your own hands, it will be easier for us to reach agreement."
