Ground Zero emergency drill staged in NYC
Hundreds of emergency employees took part in a disaster drill Sunday morning at the site in lower Manhattan where the two World Trade Center towers were struck by passenger jets and destroyed nearly eight years ago.
Officials simulated a mock explosion in a commuter train tunnel linking New York City to New Jersey.
Police and fire truck sirens sounded above ground, while emergency workers kept streets in the city's financial district closed to vehicle traffic and pedestrians. Officials also suspended PATH rail service during the drill.
About 150 volunteers pretended to be victims of the explosion.
The mock emergency involved over 800 police officers, firefighters and Port Authority of New York and New Jersey officials.
It was the largest disaster drill since the Sept. 11, 2001, attack on the twin towers, which killed more than 2,700 people.
