"We have pulled out 15 charred bodies so far. The bus was on its way to Satna from Chhatarpur," Additional Superintendent of Police R D Prajapati told PTI over phone from the accident site.
Thirteen passengers, who sustained burns, were rushed to a hospital.
Prajapati said the bus' fuel tank might have exploded after it fell down nearly 16 feet from the bridge, causing the fire.
