New York: At least four people were killed after a Metro-North Railroad train derailed in the Bronx along the Hudson River on Sunday morning, officials said.

A total of 67 people were injured, including 11 critically, a New York Fire Department spokesman, Jim Long, said.

The derailment occurred when several cars of a train headed south from Poughkeepsie, New York, left the tracks about 7.20am near the Spuyten Duyvil station under the Henry Hudson Bridge on the Hudson Line, Metropolitan Transportation Authority spokesman, Aaron Donovan, said.

At a news conference, Governor Andrew Cuomo said the operator of the train was among the people injured and was being treated. The families of the four victims had not yet been notified as of mid-morning, he said.
