Train Derails in Western Russia After Bridge Collapse, Killing at Least 7

A bridge overpass in western Russia collapsed late Saturday, derailing a passenger train underneath and killing at least seven people and injuring dozens, officials and the state news media said.

A second railway overpass also collapsed overnight as a freight train was passing over it, according to an official, but no one died. The episodes took place about 77 miles apart in regions that border Ukraine: Bryansk and Kursk.

It was not immediately clear if either railway disaster was related to the war in Ukraine.

In a separate episode, Ukraine’s military intelligence agency, the HUR, said in a statement that Ukraine had blown up a Russian military train that was traveling toward Crimea through a part of the Zaporizhzhia region occupied by Russian forces. The agency said that the train, which was carrying fuel and other cargo, derailed. The claim could not be independently confirmed.

Russian and Ukrainian delegations are scheduled to conduct the second round of face-to-face peace talks in Istanbul on Monday.

Aleksander Bogomaz, the governor of Bryansk, said in a statement that seven people died as a result of the derailment in that region. Mr. Bogomaz added that 47 people, including three children, were taken to medical facilities.

Speaking on state television, Mr. Bogomaz said that the overpass had collapsed as a result of an explosion. That could not be independently confirmed.

Russia’s road transportation agency said on social media that the destroyed overpass in the Bryansk region had train tracks below it.

Russian Railways said on social media that recovery trains were sent to help address the emergency. Videos and pictures from the scene published by Russian state news agencies showed wrecked train cars and rescue workers sifting through debris.

The area of Bryansk where the governor said the accident occurred is about 50 miles north of the Russian border with Ukraine.

Bryansk is just north of the Kursk region, the site of the other railway disaster in western Russia overnight.

Aleksandr Khinshtein, the local governor, said on social media that a bridge collapsed over a highway as a freight train was passing over it. One of the train drivers had his legs injured and was taken to a hospital, Mr. Khinshtein said.

No one else was hurt in the collapse, the Russian railway company said in a statement.

President Vladimir V. Putin of Russia visited Kursk last month after Russian troops drove Ukrainian forces out of most of the territory they had seized there in a surprise cross-border offensive.
