PALMYRA, Pa. - A fireworks accident injured 11 people gathered to celebrate Independence Day and the long-planned 250th anniversary of the borough of Palmyra in central Pennsylvania. Two people, including a child, remained hospitalized Monday afternoon with injuries that did not appear life-threatening, Palmyra police said.

"This accident occurred after one of the fireworks charges misfired, causing an explosion, sending fireworks material into a nearby crowd located near the games and ride area. ... This accident also propelled fireworks material across the football field and beyond," Palmyra police said in a news release.

The victims Sunday night suffered burns, contusions and abrasions. They included four minors between 11 and 17 and an employee of Schaefer Pyrotechnics of Ronks. A call to the company was not immediately returned late Monday afternoon.

A nursing supervisor at Penn State Milton S. Hershey Medical Center did not have any immediate updates on the victims Monday evening. Palmyra police also said no updates were available. - AP
