During the Nigerian Civil War of 1967 to 1970, the Nigerian military formed a blockade around the nation's newly independent south-eastern region, Biafra. At this time, France was one of the few major countries supportive of the Biafrans (the United Kingdom, the Soviet Union and the United States sided with the Nigerian government), and the conditions within the blockade were unknown to the world. A number of French doctors volunteered with the French Red Cross to work in hospitals and feeding centers in besieged Biafra.[1] One of the co-founders of the organisation was Bernard Kouchner, who later had a career in French politics, rising to the position of Minister for Europe and Foreign Affairs, which he held 2007–2010.[citation needed]
