Commuter train derails in the Bronx

Four deaths and dozens of injuries are reported after a Metro-North passenger train derailed early Sunday morning in the Bronx.

Fire officials told NBC News that as many as 11 of those injured were "critical" and six were in "serious condition."

A Metro-North official said there was no evidence of criminality, according to the network, but the official cautioned that it was still early in the investigation.

The National Transportation Safety Board said in a tweet that it was sending a "Go-Team to NY" to investigate the derailment.

A White House official said President Obama was briefed on the derailment on Sunday morning and will continue to be updated. Obama’s “thoughts and prayers go out to the friends and families who lost a loved one and everyone affected by this incident,” the official said.

Hudson Line service is temporarily suspended between Croton Harmon and Grand Central, the Metropolitan Transit Authority reported.

Amtrak said Sunday afternoon that service between New York and Albany, N.Y., had been restored, but delays were expected because trains were moving at reduced speeds through the area. This report was originally published at 8:36 a.m. and last updated at 3:09 p.m..
