One soldier is died, and seven others are injured, after a an explosion occurred at Fort Bragg in North Carolina.

Staff Sgt. Alexander Dalida, 32, of Dunstable, Mass., who was enrolled in the Special Forces Qualification Course at the U.S. Army John F. Kennedy Special Warfare Center and School, was announced dead on Friday, a statement form the Army Special Operations Command said.

The cause of death is still under investigation.

"Our primary focus right now is to care for his loved ones. We will honor Staff Sgt. Dalida and help his family in their time of need," said Col. Michael Kornburger, commander of the 1st Special Warfare Training Group (Airborne).

Dalida was one of eight soldiers with Army Special Operations Command who were revealed to be injured earlier in the day.

The soldiers were transported to several hospitals by medical helicopter and by ground. The explosion occurred on a Fort Bragg Range, and those involved were students and carde at the John K. Kennedy Special Warfare Center and School, an earlier statement said.

"The command is investigating the events leading up to the incident and is caring for its Soldiers and their families," Army Special Operations Command said.

The conditions of the other seven soldiers are unknown, as is the cause of the blast.

Initial reports indicated almost twice as many service members were injured in the explosion.

The accident took place just one day after 15 Marines were injured when an amphibious assault vehicle caught fire at Camp Pendleton, Calif., during "scheduled battalion training."

Some of the Marines were in critical condition but all are believed to have non-life-threatening injuries.

Both accidents occur as Pentagon leaders and lawmakers on Capitol Hill are raising alarms over a training and readiness crisis due to several years of budget cuts. Two high-profile Navy ship collisions in the Western Pacific this summer and a host of deadly aviation crashes are also being blamed on training shortfalls.

A spokesman for U.S. Army's Special Operations Command, Lt. Col. Rob Bockholt, the said all he could confirm was that an incident occurred on a training range, and the number of extent of injuries was still under investigation.

Bockholt said additional information, when available, would be posted on the U.S. Army Special Operations Command Facebook page.
