The Biafran Airlift was an international humanitarian relief effort that transported food and medicine to Biafra during the 1967-70 secession war from Nigeria (Nigerian Civil War). It was the largest civilian airlift, and after the Berlin airlift of 1948-49, the largest non-combatant airlift of any kind ever carried out. The airlift was largely a series of joint efforts by Protestant and Catholic church groups, and other non-governmental organizations (NGO)s, operating civilian and military aircraft with volunteer (mostly) civilian crews and support personnel. Several national governments also supported the effort, mostly behind the scenes. This sustained joint effort, which lasted one and a half times as long as its Berlin predecessor, is estimated to have saved more than a million lives.
By 1968, a year after the start of the Nigerian Civil War, large numbers of children were reported starving to death due to a blockade imposed by the Federal Military Government (FMG) and military. By 1969 it was reported that over 1,000 children per day were starving to death. A FMG representative declared, “Starvation is a legitimate weapon of war, and we have every intention of using it.” With the advent of global television reporting, for the first time, famine, starvation and humanitarian response were seen nightly on world television. People around the world demanded action.
International reaction to plight of the civilian population in the secessionist region was diverse. The United Nations and most national governments, expressing reluctance to become involved in what was officially considered an internal Nigerian affair, remained silent on the escalating humanitarian crisis. Secretary General of the United Nations, U Thant, refused to support the airlift. The position of the Organization of African Unity was to not intervene in conflicts its members' deemed internal and to support the nation-state boundaries instituted during the colonial era. The ruling Labour Party of the United Kingdom, which together with the USSR was supplying arms to the Nigerian military, dismissed reports of famine as "enemy propaganda".Mark Curtis writes that the UK also reportedly provided military assistance on the ‘neutralisation of the rebel airstrips’, with the understanding that their destruction would put them out of use for daylight humanitarian relief flights.
