The U.S. army psychiatrist accused of the mass shooting at Fort Hood may be paralyzed from the waist down, his lawyer says.

John Galligan told The Associated Press that Maj. Nidal Malik Hasan told him that he has no feeling in his legs, and doctors say the condition may be permanent.

Galligan said Hasan also told him he had extreme pain in his hands. He said his client's condition remains "extremely serious."

Hasan was shot by two civilian police officers who had responded to last week’s shootings.

Hasan, 39, is the only suspect in the Nov. 5 shooting rampage at the huge Texas army base that left 13 people dead and 29 wounded. He has been charged with 13 counts of premeditated murder under the American military's legal system.

He faces the death penalty if convicted.

Hospital spokesman Dewey Mitchell said he could not confirm whether Hasan was paralyzed because Hasan told hospital officials not to release any information about his condition or injuries.
