Thousands of ethnic Armenians fled the breakaway region of Nagorno-Karabakh on Monday, queuing up for fuel and jamming the mountain road to Armenia after their fighters were defeated by Azerbaijan in a lightning military operation.

The leadership of the 120,000 Armenians who call Karabakh home said Sunday that they did not want to live as part of Azerbaijan and that they would leave for Armenia because they feared persecution and ethnic cleansing.

In the Karabakh capital, known as Stepanakert by Armenia and Khankendi by Azerbaijan, crowds of people were loading belongings into buses and trucks as they left for Armenia.
