Fort Hood killings: US army probes soldier's mental health

                  Lt Gen Mark Milley describes the final moments before the gunman shot himself

The US army is investigating whether psychological trauma was the reason a soldier carried out a deadly shooting spree at a Texas military base.
The man has not been named by the army but US media have identified him as 34-year-old Ivan Lopez.
Three people were killed and 16 others wounded before the gunman shot himself dead in the attack at Fort Hood.
Officials said the shooter had served in Iraq and was being assessed for post-traumatic stress disorder.
Fort Hood's commanding officer, Lt Gen Mark Milley, said the man had not been injured when he served in Iraq in 2011 but had sought treatment for depression, anxiety and other problems.
He had arrived at Fort Hood from another base in February and was taking medication, Lt Gen Milley said.
"We are digging deep into his background, any criminal history, psychiatric history, his experiences in combat, all the things you would expect are being done right now," he told reporters. Continue.

The shooting took place at two buildings on the base at about 16:00 local time (21:00 GMT) on Wednesday.
Lt Gen Milley said the gunman walked into one of the buildings and opened fire with a .45-calibre semi-automatic pistol.
He then got into a vehicle and continued firing before entering another building and opening fire again.
It was here that he was eventually stopped by military police, shooting himself in the head when confronted by a female officer in the car park.
The shooting incident lasted between 15 and 20 minutes.
Nine of those injured are reported to be in intensive care, with three in a critical condition.

                                     The 2009 rampage left 13 soldiers dead

Officials say the weapon had been bought in a local store. Firearms are largely banned at US Army bases, with few soldiers besides military police allowed to carry them.
Mr Obama told reporters in Chicago that he was "heartbroken" by the attack, and pledged to "get to the bottom of exactly what happened".
He said Ford Hood had sacrificed so much for freedom.

"We know these families. We know their incredible service to our country and the sacrifices that they make. Obviously our thoughts and prayers... are with the entire community," he said.

The attack has brought back painful memories for military staff at Fort Hood, which was the scene of a gun rampage in 2009 that left 13 soldiers dead and 32 wounded.
Maj Nidal Hasan was sentenced to death last September for that attack - the deadliest on a domestic military installation in US history.
He claimed he had opened fire at the army base to protect Taliban insurgents from US troops who were about to be deployed in Afghanistan.
The building where the killings took place - the Soldier Readiness Building - has only recently been demolished to make way for a place of remembrance.
Another US soldier, Naser Jason Abdo, was jailed for life for plotting to blow up a restaurant full of troops near Fort Hood in 2011. The Texas native and Muslim convert said he had been inspired by Maj Hasan.
