The New York City Police Department is taking no chances with the Celebrate Israel Parade in light of tensions overseas.

Police say there are no specific threats against the parade that starts at 11 a.m. Sunday from 57th Street and proceeds up Fifth Avenue. But security will be tight, including more than 1,000 officers, bomb-sniffing dogs, sharpshooters on rooftops and radiation detection devices. Sanitation trucks filled with sand will block streets to prevent vehicle attacks.

NYPD Chief of Patrol Rodney Harrison says the precautions are in response to threats of terrorism in Israel, the Middle East and around the world. Police also are bracing for anti-Israel demonstrations.

The parade marks the 70th anniversary of the founding of Israel.
