SEASIDE PARK, N.J. (AP) — All beaches have reopened in the Jersey Shore town where a pipe bomb exploded shortly before thousands of runners were to participate in a charity 5K race to benefit Marines and sailors.

But officials won’t say if they believe the incident in Seaside Park on Saturday was terror-related or if it had any connection with an explosion that rocked a crowded Manhattan neighborhood Saturday night, injuring 29 people.

Special Agent Michael Whitaker, a spokesman for the FBI office in Newark, said state and federal investigators were still canvassing the Seaside Park area Sunday and conducting interviews. He also said travel restrictions imposed after the blast had been lifted.

Whitaker declined further comment, citing the ongoing investigation.

No injuries were reported in the explosion.

Appearing Sunday on CNN, Gov. Chris Christie said state police had “some promising leads” but no suspects.
