MOSCOW — A passenger train derailed in western Russia late Saturday, killing at least seven people and injuring 30, after a bridge collapsed because of what local officials described as “illegal interference.”

The bridge in Russia’s Bryansk region, which borders Ukraine, was damaged “as a result of illegal interference in transport operations,” Moscow Railways said in a statement, without elaborating.

Russia’s federal road transportation agency, Rosavtodor, said the destroyed bridge passed above the railway tracks where the train was traveling.

Photos posted by government agencies from the scene appeared to show passenger cars from the train ripped apart and lying amid fallen concrete from the collapsed bridge. Other footage on social media appeared to be taken from inside other vehicles that narrowly avoided driving onto the bridge before it collapsed.

Bryansk regional Gov. Alexander Bogomaz said emergency services and government officials were working at the scene. He said seven people died and two children were among the 30 injured.

“Everything is being done to provide all necessary assistance to the victims,” he said. Russian officials have not said who is responsible for Saturday’s incident, but in the past some officials have accused pro-Ukrainian saboteurs of attacking Russia’s railway infrastructure. The details surrounding such incidents, however, are limited and cannot be independently verified.

Ukrainian media outlets reported in December 2023 that Kyiv’s top spy agency had successfully carried out two explosions on a railroad line in Siberia that serves as a key conduit for trade between Russia and China. Ukraine’s security services did not comment on the reports.

Russian Railways confirmed one of the explosions described by Ukrainian media, but did not say what had caused it. There was no comment from Russian authorities on a second explosion.
