The genocide trial of former U.S.-backed Guatemalan dictator Efraín Ríos Montt has reopened under legal uncertainty. Ríos Montt is accused of overseeing the slaughter of more than 1,700 people in Guatemala’s Ixil region after he seized power in 1982. Guatemala’s top court annulled much of the case last week, sending it back to the earliest stages. The trial resumed on Tuesday, but Ríos Montt’s lawyers said the case has been thrown out and should not continue. The testimony of four witnesses from the initial trial was also thrown out. The case has been recessed until Thursday.
