The acting secretary of the United States Army announced that Major Nidal Malik Hasan, convicted of killing 13 people during a 2009 shooting at Fort Hood, Texas, will be executed by firing squad on December 3. The announcement was made via a social media post by Acting Secretary Adam Telle, confirming that the execution will take place at the military installation where the attack occurred.

Hasan’s case marks a significant development in military justice, as the U.S. military has not carried out the death penalty since 1961. Pentagon spokesperson Sean Parnell previously confirmed that President Donald Trump had authorized the execution earlier in the week.

The 2009 incident involved Hasan opening fire at Fort Hood, resulting in the deaths of 13 individuals and injuring more than 30 others. Following his conviction, Hasan was sentenced to death for the mass shooting, which has been described as one of the deadliest attacks on a U.S. military base.

The forthcoming execution underscores the U.S. military’s rare use of capital punishment and raises questions about the implementation of the death penalty within military law. Officials have indicated that preparations for the execution are underway in accordance with military protocols. Further details about the proceedings have not been disclosed.
