Heavy fighting between Azerbaijani and Armenian forces in the region since Sept. 27 has killed scores of both servicemen and civilians. Both sides have accused each other of expanding the hostilities beyond Nagorno-Karabakh.
The clashes have continued despite numerous international calls for a cease-fire.
The region of Nagorno-Karabakh lies inside Azerbaijan but has been under the control of ethnic Armenian forces backed by Armenia since the end of a separatist war in 1994.
The Los Angeles metropolitan area is home to the largest population of Armenians in the world outside of Armenia.
