The Supreme Court won't hear a challenge to the death penalty for members of the military.

The justices on Monday rejected an appeal from the former soldier who was sentenced to death for killing two fellow soldiers and injuring 14 others in an attack in Kuwait in 2003.

The appeal from Hasan Akbar focused on whether the way in which the armed forces impose a death sentence complies with recent Supreme Court rulings.

Akbar is being held at Fort Leavenworth, Kansas. He was convicted of killing Army Capt. Christopher S. Seifert and Air Force Maj. Gregory L. Stone in Kuwait during the early days of the Iraq war.

The military has not carried out an execution since 1961.
