NEW YORK (Reuters) - The smell of gas throughout much of Manhattan forced the evacuation of buildings and the suspension of a commuter train service on Monday, authorities and media reported.

There were no immediate reports of injuries.

"We are getting several calls of a foul odor. Our units are responding. It's in various parts of the city," a police spokesman said.

Part of the New York-New Jersey PATH commuter train system, which carries 225,000 passengers a day, was shut as a result.

"The service has been suspended between Hoboken and 33rd (Street) and Journal Square and 33rd pending an investigation by Con Ed and the fire department," PATH spokesman Pasquale Difulco said.

New York's CBS affiliate reported several Manhattan office buildings and schools were evacuated.
