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

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

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.
