An HH-60 helicopter crashed Thursday night at Nellis AFB, Nev. Four crew members received minor injuries and were transported to a local facility for treatment, according to a Nellis release. The crash occurred at 10 p.m. during a training mission at the Nevada Test and Training Range; the cause is under investigation. It was a hectic day at Nellis, as a civilian pilot was injured earlier that morning when an A-4 Skyhawk he was flying crashed at the base while flying red air operations.
The U.S. began extensive air and artillery strikes against Islamic State group targets in Syria on Dec. 19 in retaliation for the killing of three Americans on Dec. 13 by a gunman affiliated with ISIS, U.S. officials said.
