Nidal Hasan, convicted over the Fort Hood attack on November 5, 2009, is set to die by firing squad after President Donald Trump approved that method. ABC News said the military has not carried out an execution in more than 60 years.

The attack killed 13 people and wounded 32 others. Pentagon spokesperson Sean Parnell said the secretary of the Army will choose the time and location. The Associated Press reported that four men, including Hasan, remain on military death row at Fort Leavenworth, Kansas.
