YEREVAN - Fighting between Armenian-backed troops and Azerbaijan over the disputed Nagorno-Karabakh region flared for a second day on Sunday after clashes killed dozens, drawing international calls for an immediate ceasefire. Nagorno-Karabakh, which lies inside Azerbaijan but is controlled by ethnic Armenians, has run its own affairs with heavy military and financial backing from Armenia since a separatist war ended in 1994. But the situation along the tense 'contact line' has deteriorated in past weeks and a fresh eruption of violence on Saturday left multiple dead on both sides. The Nagorno-Karabakh military said its troops were attacked by Azeri forces at 6:00 a.m. on Sunday morning. 'The enemy continued aggressive military action, using rocket artillery and armored vehicles,' the military said in a statement. 'The army is taking necessary measures to suppress the enemy's aggressive attack offensive.'
