BREAKING: Pipe Bomb Explodes At US Marine Event... This Is Terrorism Authorities evacuated dozens of Jersey Shore homes on Saturday morning after a pipe bomb exploded where thousands of people were about to participate in a charity 5K race to benefit Marines and sailors. Investigators said they would not rule out terrorism as a possible cause. Thankfully, no injuries were reported in the blast in Seaside Park. The third annual Semper Five run was canceled, however. The pipe bomb was in a plastic garbage can when it exploded. Authorities quickly cleared the boardwalk and beach area and bomb-sniffing dogs searched the area. Investigators uncovered other devices wired together in the same garbage can that did not detonate. Weve evacuated within a four-block perimeter, spokesman Al Della Fave told the Star-Ledger. Officials said runners were expected to pass by the area around the time the blast took place, but the start of the race had been delayed due to an unattended back[ack. We have various K9s throughout the area, bomb dogs that are making sure the area is safe and secure, a law enforcement official told WCBS 880. The FBI, Department of Homeland Security, Bureau of Alcohol, Tobacco, Firearms and Explosives and the state police were all part of the investigation.
