Killed in action

More than 2,400 U.S. service members were killed in the Afghanistan war. The Pentagon said Army Staff Sgt. Ryan C. Knauss — who died from injuries suffered in the Kabul Airport bombing — was likely the final one.

After a sharp drop in 2013, the number of police and other law enforcement officers who died in the line of duty as a result of felonious incidents rose in 2014, from 27 to 51, the FBI says.

Two other American troops were wounded when a man in an Afghan army uniform opened fire, a Pentagon official said. The shooter was shot and killed.
