... 1969, Nigeria halted flights of food to Biafra, a southern, breakaway state at war with the federal government. The International Committee of the Red Cross was forbidden from continuing to coordinate aid. International pressure would persuade Nigeria to let airlifts resume, albeit under the country's rules. A half-year later rebels were defeated. The BBC reports that "it is estimated at least 500,000 -- possibly millions -- of people died of starvation and disease as a result of the war in Biafra."
