At least seven people were killed after Russian officials said “illegal interference” caused a bridge to collapse and a train to derail in Russia.

Hours later came a report of another bridge collapse, also in western Russia, involving a freight train. 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.

Two bridges have collapsed in Russia’s western regions bordering Ukraine, killing multiple people and injuring dozens, authorities said.
