Another attempt at a mass casualty attack in the USA.
A device exploded in Seaside Park, New Jersey, Saturday morning as about 5,000 runners were set to participate in a 5k Marine charity race and police are investigating another suspicious device found in the shore town, authorities said.
The explosive device went off in a garbage can on D Street and Ocean Avenue at about 9:30 a.m., police said.
The bomb was supposed to detonate a second device which failed to go off, but would likely have increased the potential for lethality and damage.
Police are also investigating another "suspicious package" in Seaside Park.
