An Amtrak passenger train derailed in Washington state on Monday morning, injuring and killing an unknown number of people.
The derailment happened 40 miles south of Seattle, on a bridge over a major highway, the AP reported. The crash blocked all southbound lanes on Interstate 5 and prompted a massive emergency response, according to local authorities and news media reports.
