An aerial footage shot by a drone shows an outline of an airplane in the snow at the Sergey Prokofiev International Airport damaged by shelling during fighting between pro-Russian separatists and Ukrainian government forces, in Donetsk, eastern Ukraine, seen in this still image taken Jan. 15, from handout video by Army.SOS, a Ukrainian group that supports the army by buying ammunition, food and supplies for soldiers. Fighting raged on Saturday at the main airport of Ukraine's city of Donetsk as separatists resumed attempts to break the tenuous grip of government forces on the complex and Kiev's military said three more Ukrainian soldiers had been killed.
