An explosion has rocked central New York during the evening rush hour, forcing the evacuation of nearby streets and Grand Central Station.
Officials said a number of people had been taken to hospital after being hurt when a steam pipe ruptured underneath Lexington Avenue in Manhattan.
The New York Police Department said the incident, which blew a large hole in the street, was not terrorism-related.
Police said there were unconfirmed reports of six people injured.
Millions of pounds of steam are pumped beneath the streets of New York, heating and cooling thousands of buildings. In 1989, three people were killed when a steam pipe ruptured in the city.
