Brisbane, Muharram 21, 1436, Nov 14, 2014, SPA -- The civil war in eastern Ukraine, which has claimed more than 3,600 lives, has cast a shadow over the summit of the world's 20 major economies and industrializing nations being held in Brisbane, dpa reported. The situation in the Donbass region, where Ukrainian government forces and pro-Russian separatists are confronting each other, is threatening to escalate despite a ceasefire agreed at the start of September. The conflict turns on how the former Soviet republic will align itself along the fault line between the European Union and Russia. -- SPA 19:06 LOCAL TIME 16:06 GMT www.spa.gov.sa/1295021
