Armenia and Azerbaijan say they have agreed on a cease-fire in Nagorno-Karabakh starting Saturday

MOSCOW (AP) — Armenia and Azerbaijan agreed to a Russia-brokered cease-fire in Nagorno-Karabakh starting Saturday, but immediately accused each other of derailing the deal intended to end the worst outbreak of hostilities in the separatist region in more than a quarter-century. The truce would have marked a major diplomatic coup for Russia. But minutes after it entered force, Armenia and Azerbaijan accused each other of breaching the cease-fire with new attacks. The latest outburst of fighting between Azerbaijani and Armenian forces began Sept. 27 and left hundreds of people dead in the biggest escalation since a separatist war there ended in 1994. Nagorno-Karabakh lies in Azerbaijan but has been under control of ethnic Armenian forces backed by Armenia.
