A bus has caught fire in north-western Kazakhstan, killing 52 people, the interior ministry has said.
Five people managed to get out and were treated by rescue workers on the spot, reports said.
The accident happened at 10:30 local time on Thursday in the Irgiz district of Aktobe region.
The bus is thought to have been carrying Uzbek citizens to or from Russia along the Samara-Shymkent route, said local media.
The route, which is about 2200km long, is frequently used by Uzbek migrant labourers travelling to construction sites in Russia, observers said.
The emergency services ministry told AFP news agency that 55 passengers and two drivers had been aboard the bus.
"Five passengers received medical assistance. The remainder were killed," it said in a statement.
But the causes of the deadly blaze are so far unclear.
Emergency officials have opened a telephone hotline for worried relatives.
