At least four people were killed and 63 injured after a Metro-North passenger train derailed on a sharp curve in the Bronx borough of New York City on Sunday morning, officials said.
Eleven people were in critical condition at area hospitals, according to New York Governor Andrew Cuomo, although he said he believed they were in stable condition. Three of the dead were ejected from the train. Several people had to be extracted from the wreckage.
"Obviously a very tragic situation," said Cuomo, who declined to speculate on the cause of the crash. "The first order of business is to care for the people on the train."
Cuomo said that the train's operator had survived the crash and was being treated for unspecified injuries.
