DONETSK, UKRAINE - AUGUST 14:  Residents of Donetsk sit in a shelter in the Topaz district after fleeing the nothern suburbs near the international airport as the ongoing artillery battle between the Ukrainian forces and pro Russian rebels intensifies on August 14, 2014 in Donestk, Ukraine.  A Russian aid convoy is on its way towards the Ukranian border, heading to a crossing controlled by pro-Russian rebels instead of a government controlled post which the Ukrainian government has demanded it head to, according to the latest reports. The government has threatened to block the convoy if the cargo could not be inspected and is sending its own cargo of aid to the war-torn region of Luhansk. (Photo by Pierre Crom/Getty Images)
