NORTH MYRTLE BEACH, S.C. — A worker at a July Fourth fireworks show in South Carolina's North Myrtle Beach was hurt after a shell exploded prematurely.

City spokesman Pat Dowling says part of the Cherry Grove Pier was damaged in the blast Thursday evening.

The man was taken to a hospital in Myrtle Beach for treatment. There was no word on his condition early Friday. His name hasn't been released.

Dowling says the show ended after just six minutes because of the explosion.

Dowling says the blast put a hole in the pier and damaged part of the railing.

The incident happened the same night more than two dozen people northwest of Los Angeles were injured when a wood platform holding live fireworks tipped over, sending the pyrotechnics into a crowd at a 4th of July show.
