Fort Hood shooting probe

Senior US Senator, Joe Lieberman said he plans to open a congressional investigation into last week\'s deadly shooting at Texas army base, Fort Hood.



Mr Lieberman, who chairs the Senate Homeland Security Committee, said he wants to find out whether it was a terrorist attack.



Nidal Malik Hasan, a Muslim army major, is suspected of killing 13 people.



Mr Lieberman also said he hopes to determine whether the army missed signs that Major Hasan harboured extreme views.



The 39-year-old army psychiatrist opened fire at the Fort Hood base on Thursday.



Besides those killed, 29 people were wounded.



Maj Hasan was shot by a police officer and remains in a coma.
