Azerbaijan has launched fresh air raids on the capital of the disputed territory of Nagorno-Karabakh, as a Russia-backed ceasefire between Azeri and Armenian forces broke down less than a day after it was implemented Friday. Armenia accused Azerbaijan of deliberately targeting a historic cathedral, while Azerbaijan accused Armenia of shelling a residential area in its second-largest city, Ganja. At least 300 people have been killed since fighting in the territory erupted two weeks ago.
