A military helicopter flies above a Russian convoy of trucks carrying humanitarian aid for Ukraine, parked at a camp near Kamensk-Shakhtinsky, Rostov Region, August 14, 2014. Artillery shells hit close to the centre of Ukraine's separatist-held city of Donetsk for the first time on Thursday, killing at least one person, as a large Russian aid convoy rumbled towards the border.
