A US military official Tyler Broadway on Friday said one more person injured during a shooting rampage at Fort Hood in Texas had died.
Broadway said early Friday that the toll now stands at 13 dead and 30 wounded. Late Thursday, officials said 12 people had been killed and 31 wounded in the afternoon attack.
The suspected shooter, Maj. Nidal Malik Hasan, was on a ventilator and unconscious in a hospital late Thursday. The Army psychiatrist was shot four times after the rampage began around 1:30 p.m.
The motive for the shootings isn't clear, but Hasan was apparently set to deploy soon. He also had expressed some anger about the wars in Iraq and Afghanistan.
