The bus was travelling along a road in Kazakhstan’s north-western Aktau region that links the Russian city of Samara to Shymkent, a city in southern Kazakhstan close to the Uzbek border.
It was unclear in which direction the bus had been travelling, but the route is widely used to transport Uzbek migrant workers to and from Russia where they often take on work on building sites.
Only five people managed to escape the burning vehicle, the interior ministry’s emergencies department said in a statement. The ministry said the apparent accident had happened at 10:30 local time (4:30 GMT), but provided no details about its cause.
An Instagram user shared video footage of the fire on his account.
