Authorities say a pipe bomb exploded in a Jersey Shore town shortly before thousands of runners were due to take part in a charity 5K race to benefit marines and sailors. No injuries were reported in the blast in Seaside Park, which occurred around 9:30am Saturday, according to the AP. The race—the third annual Semper Five run—was canceled. The pipe bomb was in a garbage can when it exploded. Authorities immediately cleared the boardwalk and beach area. Officials say runners had been scheduled to pass by the area around the time the blast occurred, but the start of the race had been delayed after an unattended backpack was found.
New Jersey State Police say there was nothing to reports of a second explosive device nearby. Also, they say, bomb technicians have "rendered safe" the items located in a plastic trash can where the explosion occurred. (Read more pipe bomb stories.)
