LAS VEGAS — The Air Force says a helicopter on a training mission has crashed near Las Vegas and four crew members were treated for minor injuries.

The HH-60 attached to Nellis Air Force Base went down about 10 p.m. PDT Thursday on the Nevada Test and Training Range, near Las Vegas.

The military says the four crew members were transported to a medical facility and treated for minor injuries.

No further information was immediately released on their conditions or on how the crash occurred.

Nellis officials say there is no connection to another crash several hours earlier during which a pilot ejected with minor injuries after a fighter jet went down near the air base after completing an exercise with a military weapons school.
