Former head of Argentine air force on trial for abduction

BUENOS AIRES, Argentina (AP) — The former head of Argentina's air force and two ex-subordinates are on trial for alleged abduction and disappearance of activists during the South American nation's 1976-1983 dictatorship.

Omar Graffigna, who today is 90 years old, is accused of abducting activist couple Patricia Roisinblit and Jose Manuel Perez Rojo in 1978.

Roisinblit was eight months pregnant when she, Perez Rojo, and a 15-month-old daughter were taken to a clandestine detention center. What happened to the couple is unknown.
