FORT HOOD, Texas (AP) President Barack Obama and first lady Michelle Obama have taken the stage at the military memorial honoring those killed in the Fort Hood shootings last week.

The national anthem played after their arrival, and the soldiers in the crowd of about 15,000 stood at attention. In a prayer opening the ceremony, each slain victim was named by first name.

Already on the stage were several soldiers wounded in Thursday's shootings at Fort Hood. Some had made their way to the stage on crutches, one was in a wheelchair and they were joined by victims' relatives.

At the front of the platform stood a row of battlefield crosses, the traditional soldier tribute to the fallen: Pairs of boots, a rifle protruding straight out of one of the boots and a combat helmet resting atop the weapon. In front of each set of boots was a photo of each victim.
