How many people were shot in the military base in Texas?

Thirteen people are now confirmed dead in the shooting at an American military base in Texas. Thirty-one others were wounded. Officials say the suspected gunman Major Nidal Malik Hasan is being treated at a hospital after being shot four times. Officials are praising a civilian policewoman for ending the shooting Thursday at Fort Hood. An army official told reporters Friday that Kimberly Munley exchanged gunfire with the suspect after he began shooting. The policewoman and the rest of the wounded are also hospitalized. The reason for the attack remains unclear. Major Hasan is an army psychiatrist. He was said to be opposed to the wars in Iraq and Afghanistan.
