Eight people were hurt, one of them seriously, in an explosion at a New Jersey naval station Tuesday, officials said.
The U.S. Navy said crews were doing routine maintenance on a utility boat at Earle Naval Weapons Station in Monmouth County about 9 a.m, when the explosion occurred.
Ammunition operations at the weapons station weren't affected by the explosion, and the damage was contained to the boathouse, the U.S. Navy said. The exact cause of the blast is still under investigation.
All of the victims were taken to hospitals, primarily with minor injuries related to smoke inhalation. One of the workers has already been released from the hospital. The other six are still being evaluated by doctors.
The station is in Leonardo, N.J. on Sandy Hook Bay.
