Military officials say a lightning strike has injured 10 soldiers from a New Jersey Army National Guard unit who were training at Fort Drum in northern New York.

First Sgt. David Moore tells The Associated Press that the soldiers from the Lawrenceville-based 50th Infantry Brigade Combat Team were on a training ground on the Army post when the lightning struck around 8:30 p.m. Tuesday.

Moore says six of the soldiers were checked out by medical staff and have returned to duty. He says the other four are under the care of the unit's medics and are expected to resume their duties.

About 2,000 members of the 50th Infantry are at Fort Drum for its annual 15-day training exercise that began last weekend.

Fort Drum is home to the 10th Mountain Division.
