MADRID — A Spanish judge has indicted six Chileans and an American for their alleged role in the 1976 kidnapping, torture, and murder of Spanish U.N. official Carmelo Soria in Chile.

Judge Pablo Ruz charged the seven with genocide, murder, and kidnapping in the National Court indictment released Tuesday. He issued international arrest warrants for them.

The seven worked for the DINA, the Chilean secret police agency under then dictator Gen. Augusto Pinochet. They include former DINA director Juan Contreras who is imprisoned in Chile.

The American was named as Michael Townley, a former DINA agent who served five years in a U.S. prison for complicity in the assassination in Washington of former Chilean Ambassador Orlando Letelier and his assistant in 1976.

Townley later was put in U.S. witness protection program.
