An American soldier has shot dead three people and injured at least 16 before taking his own life at the U-S' biggest army base in Texas.
General Milley said the suspected soldier had been later found in a parking lot with a self-inflicted gunshot wound in the head. He said the soldier--identified as Ivan Lopez-- had mental health issues and was receiving treatment. Lopez, who was an specialist in the U-S army, had served for four months in Iraq in 20-11. General Milley said all the victims were military and that the motive behind the killings is not known. Other security officials said the shooting was apparently not linked to terrorism. Meanwhile, President Barack Obama has vowed to get to the bottom of the shooting at Fort Hood which was the scene of another deadly shooting rampage in 2009.
