WASHINGTON (AP) — A federal jury has found an Afghan enemy combatant guilty of drug charges in what the Justice Department calls the first convictions under new narco-terrorism laws.

Prosecutors say heroin dealer Khan Mohammed also was an arms trafficker who targeted Afghans and U.S. personnel in Afghanistan. He was held as an enemy combatant before he agreed in 2006 to face trial in the United States.

A jury in U.S. District Court in Washington found Khan guilty on Thursday of securing heroin and opium bound for the United States and, in doing so, assisting terrorism activity.
