The truck accident on May 29 sparked riots in the Afghan capital, in which at least eight people were killed and 120 injured.
The U.S. military today said its initial investigation shows that U.S. troops, confronted by hostile rioters after the truck crash, opened fire in self-defense.
Authorities have arrested scores of people suspected of involvement in the riots. They are also investigating whether political groups encouraged the violence.
