WASHINGTON - Suicides are a serious problem at the huge Texas military base in Fort Hood, Texas, where an Arab-American officer went on a spree on Thursday, records show. According to The Washington Post, 10 of the 117 active-duty Army soldiers reported to have committed suicide this year were stationed at Fort Hood and 75 have taken their lives there since 2003. Fort Hood is the Armys largest base, with tens of thousands of soldiers, but the number of suicides also is the highest among US military posts, the newspaper said. The alleged shooter in Thursdays rampage that left 13 dead and 30 wounded was Maj Nidal Malik Hasan, 39, a psychiatrist known to be working with soldiers returning from overseas combat with emotional problems. Hasan, a Muslim of Jordanian descent, allegedly had been upset about his impending deployment to Afghanistan. He was under guard and in stable condition on a ventilator after being shot and seriously wounded in the attack, officials said. Meanwhile, the US Army said Friday it is committed to treating all its soldiers with respect without regard to their religious identity, amid concern about a possible backlash after Thursdays shooting incident. We always have a deep and enduring concern that everybody be treated with dignity and respect, army spokesman General Kevin Bergner told reporters. We spend a lot of time on that specific issue, whether its ethnic, religious, racial (identity), he said. That is an enduring and sustained part of our commitment for our soldiers, civilians and our families. He said he did not have any details yet about how the military would seek to promote tolerance and contain possible tensions in the wake of the rampage. Bergner also he did not know if the army planned any security measures to protect Muslim members of the armed services. Muslim-American groups quickly condemned the shootings and the Council on American-Islamic Relations (CAIR) urged the nation to remain calm and unified. The Washington Post said multiple deployments through years of war in Afghanistan and Iraq have produced record rates of mental health problems in the all-volunteer Army. About 30 percent of those returning from combat suffer mental health symptoms, including depression, anxiety and post-traumatic stress. Abuse of alcohol and drugs is on the rise. The newspaper points out that those who treat soldiers with post-battlefield emotional issues have been known to experience symptoms vicariously. Hasan, who served a psychiatry internship at Walter Reed Army Medical Centre from June 2003 to this past July, treated soldiers with post-traumatic stress disorder. Meanwhile, investigators on Saturday worked to uncover the motives of a Muslim army doctor suspected of killing 13 people in a shooting. An initial search of Major Nidal Malik Hasans computer revealed no direct exchanges with known extremists, but US Army and FBI officials had yet to rule out possible links to terrorist groups, US media reported. Earlier this year, the Federal Bureau of Investigation learned of Internet postings by a man calling himself Nidal Hasan that expressed support for suicide bombings. Investigators were not able to determine yet whether the writer and Major Hasan were the same person, but the details fuelled concerns that authorities may have missed warning signs prior to the attack at Fort Hood, Texas. Neighbors reportedly said Hasan, 39, was in a rush when he gave away his belongings shortly before Thursdays bloody shooting spree. Im not going to need them, he told one neighbour, Patricia Villa, according to The New York Times, handing over bags of vegetables, a mattress and clothing. Hasan had voiced dismay over US wars in Islamic countries and was distraught that he was about to be deployed to Afghanistan. He reportedly said the US struggle against terror threats was a war on Muslims, while his family alleged he was the target of prejudice and harassment over his Islamic faith.
