UPDATE IV

Malik Nadal Hasan, the US Army major who allegedly shot dead 12 people and injured 31 others in a rampage at the army base in Fort Hood, is alive and was likely the lone shooter behind the deadly incident, military officials say.

"The evidence does not suggest" that this was a terrorist act, Lt. Gen. Bob Cone told the press Thursday evening.

The officer said Hasan is hospitalized and is in stable condition after being shot by a first responder. "His death is not imminent," Cone said.

That first responder, a female civilian police officer, was initially reported to have died in the shootout. She is now reported to be in stable condition in hospital.

Lt. Gen. Cone explained that the high casualty count was due to the fact that the shooting took place in two adjacent facilities that were crowded with military personnel. And the shooter may have had a semi-automatic rifle, the lieutenant-general said. Initial reports suggested the shooter had been armed only with two handguns.

Media reports over the course of the day indicate that Hasan was an army psychiatrist who had been promoted to major in May, and was due to ship out to Iraq. Some news stations reported that Hasan was upset about his deployment.

ABC News reports that Fort Hood has lost more soldiers in the Iraq war than any other US military base. Since the war began, 482 Fort Hood soldiers have lost their lives in Iraq. Some 15,000 Fort Hood soldiers are deployed in Iraq at present.

UPDATE III

Officials are confirming that 12 people have been killed and 31 wounded at the army base at Fort Hood, Texas.

Lt. Gen. Bob Cone told a press conference that all the deaths took place in the base's readiness facility, where soldiers are prepared for deployment. A civilian police officer was among the casualties.

Cone confirmed that one shooter was killed on the scene. That person's identity has not officially been released, but ABC News had identified him as Major Malik Nadal Hasan.

Authorities have two other suspects in custody, but have not said if they were involved in the incident.

President Barack Obama described the incident as "a horrific outburst of violence" at the end of a speech to Native Americans.

"My immediate thoughts are with the wounded and the families of the fallen, and those who live and serve at Fort Hood," the president said. "It's difficult enough when we lose these brave Americans in battles overseas. It is horrifying that they should come under fire on an army base on home soil."

Obama said the Pentagon, the FBI and Homeland Security are all involved in the response to the tragedy.
