WACO, Texas (AP) - An AWOL soldier accused of plotting to bomb Fort Hood soldiers has been indicted on a charge of trying to use of a weapon of mass destruction.
    
It's part of a six-count superseding federal indictment returned by a grand jury Tuesday against Pfc. Naser Jason Abdo. He faces up to life in federal prison if convicted.
    
He was indicted in August on three federal charges related to trying to bomb soldiers in restaurants near the Texas Army post this summer. The maximum penalty for each of those charges is 10 years in prison.
    
Authorities say they'll try him on the six new charges first - including attempted murder of officers or employees of the United States.
    
Abdo remains in federal custody in Waco.
    
There's a gag order in the case.
