INSIDE TRACK ON WORLD NEWS by international syndicated columnist & broadcaster Eric Margolis
Aussaresses admits he and his team of `specialists' conducted one of the war's most notorious crimes: the 1955 mass slaughter of Algerian suspects in revenge for attacks on French settlers. `Action service' ran a secret torture center at the Villa les Tourelles in Algiers where Aussaresses personally supervised interrogations. Thousands of Algerians were subjected to `la gégène,' intense electric current delivered to genitals, ears, and lips, savage beatings, near-drowning in filthy water, and mock executions. Few suspects ever emerged alive.
