The NYPD has tight security plans for Sunday’s annual Celebrate Israel Parade, deploying 70 “blocker vehicles” and thousands of officers to secure the Fifth Avenue route, authorities said Friday.

Officials said there are no credible threats to the event, which will start at 11 a.m. on 57th Street and end on 74th Street.

Still, “given the current threat level in Israel and the Middle East as well . . . we are not taking any chances,’’ said Chief of Patrol Rodney Harrison.

The personnel will include radiation-detection teams and bomb squads, according to NYPD counterterrorism chief John Miller.
