Three Fort Stewart soldiers are being treated for injuries from an explosion inside an armored vehicle on the southeast Georgia Army post.

Fort Stewart spokesman Kevin Larson said Wednesday none of the injuries are life-threatening. One soldier was taken to the Augusta burn center with second-degree burns. The others were treated at Fort Stewart for minor burns and dehydration.

Larson said the soldiers were driving an M-88 armored vehicle on a tank trail when they heard a hissing sound, followed by an explosion inside the crew compartment. The blast threw one of the soldiers out of the vehicle.

The M-88 is an armored tow truck used to move tanks and other heavy vehicles. The Army is investigating what caused the blast.

The soldiers' identities were not immediately released.
