Habre's security forces were trained by key American allies, including Israel and Saudi Arabia

"Brought to power by covert CIA support under the Reagan administration, Habre's security forces were trained by key American allies, including Israel and Saudi Arabia. Habre used them generously and lethally: His secret police are accused of killing some 40,000 people in political prisons between 1982 and 1990, according to findings by a Chadian truth commission. An additional 200,000 had been unjustly imprisoned and tortured." (thanks Basim)
