MOSCOW — Commonwealth troops went on alert Thursday after fighting erupted between Armenians and Azerbaijanis in an enclave bordering Turkey. At least 20 people were reported killed and 100 wounded in the latest escalation of the 4-year-old war.
Iran also agreed Thursday to send observers to help end border fighting between Armenians and Azerbaijanis.
The outbreak of fighting in Nakhichevan follows Armenian victories this week in the bloodiest conflict in the former Soviet lands: the battle for control of Nagorno-Karabakh. The region within Azerbaijan is populated mainly by Armenians who want independence or alliance with Armenia.
