Texas ? An Army psychiatrist who may face the death penalty after the mass shooting at Fort Hood was charged Wednesday with 32 counts of attempted premeditated murder relating to the scores of soldiers and two civilian police officers injured in the attack, military officials said.

Maj. Nidal Hasan has already been charged with 13 counts of premeditated murder after the Nov. 5 shooting in a building at the Texas Army post where soldiers must go before being deployed. Witnesses said he jumped on a desk and shouted “Allahu Akbar!” — Arabic for “God is great!” Army officials have said he was armed with two pistols, one a semiautomatic capable of firing up to 20 rounds without reloading.

The additional charges come less than 24 hours after Hasan’s civilian attorney was notified that the Army plans to evaluate Hasan to test his competency to stand trial as well as his mental state at the time of the shooting.
