At least 11 people were killed when a bus and a truck collided in Eastern Siberia's Krasnoyarsk region in Russia, a spokesman of the regional Interior Ministry has said.
"Eleven people have died, at the moment we have data that 22 people have been injured, but the information is changing," Vladimir Yurchenko said on July 22.
The road accident occurred on the federal highway M-53 "Baikal."
The shuttle bus, which was carrying 50 passengers, is owned by the Krasnoyarsk-bed firm Motor Column 1967.
Police have seized company documents as part of their probe.
A medical helicopter was dispatched to the scene.
"The passengers who sustained serious injuries will be delivered to the clinical hospital in Krasnoyarsk," regional Health Ministry spokeswoman Yanina Strelkovskaya said.
Three people were taken to the Center for Disaster Medicine in Achinsk; six others were taken to Kozulsk central district hospital.
Russia's Investigative Committee says it has opened two criminal cases over the collision.
The Russian Emergency Situations Ministry opened a telephone hotline for relatives of the passengers, and Krasnoyarsk Governor Viktor Tolokonsky flew to the scene of the accident.
