YEREVAN, Armenia (AP) — An explosion at a crowded gas station in Azerbaijan's Nagorno-Karabakh region left scores of people dead and injured as thousands of ethnic Armenians rushed to flee into neighboring Armenia, the separatist territory's authorities said Tuesday.

Some 28,000 people — about 23% of the region's population — have fled across the border since Azerbaijan in a swift military operation last week, according to Armenia's government.
