An Argentine former army general from the country's 1976-1983 dictatorship has been on trial on charges of kidnapping, torturing and murdering leftist opponents of the regime. Luciano Benjamin Menendez, 80, and seven other military officers are being prosecuted for the killing of four members of the leftist Revolutionary Worker's Party (PRT) in 1977. "Now it's your turn" cried one of the relatives of the victims, pointing at Menendez and the alleged co-conspirators. Menendez, nicknamed "Cub" or "The Hyena of La Perla," commanded the Third Army Corps between 1975 and 1979, with authority over much of central and northeastern Argentina.
