Iraq was ordered to destroy its chemical and biological weapons and the UN attempted to compel Saddam's government to disarm and agree to a ceasefire by imposing additional sanctions on the country in addition to the initial sanctions imposed following Iraq's invasion of Kuwait. The Iraqi Government's failure to disarm and agree to a ceasefire resulted in sanctions which remained in place until 2003. The effects of the sanctions on the civilian population of Iraq have been disputed. Whereas it was widely believed that the sanctions caused a major rise in child mortality, recent research has shown that commonly cited data were fabricated by the Iraqi government and that "there was no major rise in child mortality in Iraq after 1990 and during the period of the sanctions." An oil for food program was established in 1996 to ease the effects of sanctions.
