Eight people have died and more than 30 others were injured when a bus carrying Armenian nationals overturned in central Russia.
Officials in Russia's Tula region said the bus was traveling to the Armenian capital, Yerevan, with 59 passengers on board when the accident occurred late on November 2.
A police statement said the driver "lost control" of the bus and that the most likely reasons for the crash was that the driver fell asleep or there was a technical fault with the bus.
The spokesman for Tula’s Interior Ministry, Andrei Yartsev, said the two drivers in the bus were being questioned by police as two criminal probes were launched into possible traffic safety violations.
Yartsev also said a number of passengers were in serious condition in hospital.
