One person died and four others were critically injured when a truck carrying fireworks exploded on an island in North Carolina on Saturday, authorities said.

Jamie Tunnell, spokeswoman for Hyde County, North Carolina, said the fireworks were to be used for the evening's Fourth of July fireworks show on Ocracoke Island, and the dead person and the four wounded were members of a crew involved in setting up the display.

The truck exploded at the island's docks.

Emergency crews and firefighters were called to the scene and two of them were being treated for smoke inhalation and exhaustion.

The Ocracoke Island can be reached only by ferry, private boat or plane.

After the explosion, ferry service to the island was suspended.

The Federal Bureau of Investigation, and the Bureau of Alcohol, Tobacco, Firearms and Explosives will participate in the investigation.
