UPDATE: Soledad Canyon Wildfire

New Mexico – Fort Bliss officials say firefighters are gaining ground on a wildfire that's blackened more than about five thousand acres of a southern New Mexico section of the Army post.

An air-and-ground attack has contained 60 percent of the wildfire.

Federal, Army and New Mexico state crews continue to fight the blaze in the rugged Organ Mountains, about 12 miles east of Las Cruces, N.M., but no structures are threatened and no one has been injured.

The fire was ignited by a training exercise. The battle to contain the flames has been complicated by unexploded ordnance in the Fort Bliss firing range, which extends from El Paso into southern New Mexico.
