(NEW YORK) -- The New York Police Department will begin a five-day drill Tuesday to test its preparedness against a dirty bomb attack on the city.
The drill will take place over five days, involve hundreds of personnel from 150 agencies, and will cost millions of dollars that the city and the U.S. Department of Homeland Security hope will help prevent a dirty bomb attack on New York by land or by sea.
The exercise will begin at the United Nations and spread into the Bronx, Long Island and parts of Connecticut and New Jersey.
Officials maintain that the drill is not the result of a specific threat.
