YEREVAN, Armenia (AP) — Armenia accused Azerbaijan of firing missiles into the capital of the separatist territory of Nagorno-Karabakh, while Azerbaijan said several of its towns and its second-largest city were attacked. Iran, which borders both countries, said it was working on a cease-fire plan in the decades-old conflict but also warned against any fighting spilling into its territory. The conflict reignited Sept. 27 and killed scores of people on both sides. Nagorno-Karabakh lies in Azerbaijan but has been under control of ethnic Armenian forces backed by Armenia since the end of a separatist war in 1994. Residents of Nagorno-Karabakh told a Russian news agency that parts of the territorial capital were suffering shortages of electricity and gas after the strikes.
