The FBI says that a US Army Major suspected of killing 13 people was not part of a broader terrorist plot. Major Nidal Hasan was noticed by the FBI in December last as part of an unrelated inquiry by the Joint Terrorism Task Force, but did not raise concerns. Investigators said that his communications with another person were in line with his job as an army psychiatrist. Maj Hasan is in hospital and has regained consciousness after being shot by police during the attack last week. Thirteen people were killed and 29 injured in the shooting at Fort Hood base in Texas on Thursday.<br/>
