SHUSHA, Azerbaijan (Reuters) - Corpses of ethnic Armenian soldiers lined stretches of a mountain road in Nagorno-Karabakh on Friday as Russian peacekeepers in trucks and armoured personnel carriers moved in after a peace deal between Armenia and Azerbaijan.Russia is deploying almost 2,000 troops along with tanks and other armour to secure a truce agreed this week after a six-week war over the ethnic Armenian enclave in Azerbaijan and surrounding areas in which Turkey-backed Azeri forces captured swathes of territory. The scale of the destruction on Friday showed how desperate the fighting had become. One Russian column, accompanied by Reuters reporters from the Armenian border, drove past around a hundred dead ethnic Armenian soldiers strewn by the roadside. One soldier lay prostrate in the middle of the road as the convoy laboured up a hill.
