The last bus carrying ethnic Armenians from Nagorno-Karabakh has left the region, completing a weeklong, grueling exodus in which more than 80% of its residents have fled after Azerbaijan reclaimed the area in a lightning military operation last month.

Azerbaijan's prosecutor general says the country has issued an arrest warrant for former Nagorno-Karabakh separatist leader Arayik Harutyunyan.

Lawmakers in a breakaway Armenian-populated region of Azerbaijan have elected a new separatist president in a move that was strongly condemned by the Azerbaijani authorities.
