A third attempt at halting weeks of fighting over Nagorno-Karabakh collapsed quickly yesterday with Armenia and Azerbaijan trading accusations of violating the US-brokered ceasefire within minutes. The latest "humanitarian ceasefire" was announced by Washington on Sunday, after truces brokered by Russia and France fell apart over previous weekends. Azerbaijan's foreign ministry said Armenian forces had shelled the town of Terter and nearby villages in "gross violation" of the truce. Armenia's defence ministry said Azerbaijani forces had "grossly violated" the ceasefire with artillery fire on combat positions in various parts of the frontline. More than 1,000 people have been reported dead in the fighting which brokeout on September 27.
