Pro-Russian rebels in eastern Ukraine say that at least 30 of their colleagues have been killed after a day of heavy fighting in the city of Donetsk that included air strikes against insurgents who attempted to seize the city’s airport.  A rebel fighter, who wouldn’t give his name because of security concerns, told the Associated Press outside a hospital in Donetsk that 30 bodies of his fellow insurgents were delivered there. He said the truck carrying the bodies was still parked outside the hospital, waiting for explosives experts to check it for any unexploded ordnance.
