Thirteen people have been killed and another thirty wounded at a US military base in Texas in what’s believed to be the worst mass killing of its kind in the nation’s history. Military officials have identified an Army psychiatrist named Major Nidal Malik Hasan as the suspected shooter in the attack at Fort Hood. Hasan was originally reported to have been shot dead, but officials now say he is hospitalized in stable condition. A relative told reporters Hasan had complained of being harassed for being a Muslim and had tried to leave the military.
