Recently declassified U.S. documents provide „conclusive“ evidence that Chilean dictator General Augusto Pinochet ordered the killing of one of his leading opponents in the streets of the U.S. capital in 1976, a son of the victim said on Thursday.

Orlando Letelier was assassinated, along with his 25-year-old American co-worker Ronni Moffitt, by a car bomb in the center of Washington, D.C. in 1976.
