Iraq's armed forces were devastated during the war. Shortly after it ended in 1991, Kurdish Iraqis led several uprisings against Saddam Hussein's regime, but these were successfully repressed using the Iraqi security forces and chemical weapons. It is estimated that as many as 100,000 people, including many civilians were killed. During the uprisings the US, UK, France and Turkey, claiming authority under UNSCR 688, established the Iraqi no-fly zones to protect Kurdish population from attacks by the Saddam regime's fixed-wing aircraft (but not helicopters).
