A United Nations mission has arrived in Nagorno-Karabakh following an Azerbaijani takeover of the mountain enclave that resulted in the exodus of the region's ethnic Armenian population. An Azerbaijani presidential spokesman said the mission arrived early on October 1 to assess the humanitarian needs in the region. It marks the first time in about 30 years that the UN has gained access to the region. Ethnic Armenians, who had controlled Nagorno-Karabakh for three decades, agreed to disarm and dissolve their government following an Azerbaijani offensive last week. Nearly all of Karabakh's estimated 120,000 residents have fled the territory for Armenia in recent days.
