At least 16 people were killed on Friday when a train slammed into a bus that had broken down on a level crossing east of Moscow, authorities said.
The collision occurred before dawn on Friday near the town of Pokrov, some 110 kilometres (70 miles) from the Russian capital.
“According to preliminary information, 16 people, including a child, have been killed,” Russia’s Investigative Committee said.
“Other passengers, including minors, have been taken to hospital with various injuries. The number of dead and injured is being ascertained,” the committee said, confirming it had opened an investigation.
The regional interior ministry said the bus broke down on the level crossing.
Uzbekistan’s foreign ministry said in a statement that 19 Uzbek nationals had died in the crash, despite the Investigative Committee reporting a lower figure.
The train, travelling at 90 kilometres per hour from the second city of Saint Petersburg to Nizhny Novgorod, east of Moscow, slammed into the bus at 3:29 am (0029 GMT) on Friday.
The train was 400 metres (yards) away from the crossing when the driver slammed on emergency brakes and sounded a warning alarm, but it was not able to stop before it hit the vehicle, Russian Railways said.
All victims on the bus
All of those killed were on the bus, which was carrying 58 people, 56 of them Uzbek nationals.
The remaining two were drivers from Kazakhstan.
“There are no victims among the train passengers,” the interior ministry said.
Images from the scene showed the white Mercedes bus had been almost completely torn apart with most of its roof ripped off and debris scattered across the tracks.
