內戰爆發的最初幾週,奈及利亞政府為切斷比亞法拉透過外匯交易、郵件、電信,以及所有海港與機場的對外聯繫管道,決定對該政權實施封鎖。起初,外界無法確定奈及利亞海軍當時擁有的船艦是否能有效封鎖長達200英里(320公里)的海岸線,以及奈及利亞空軍(英语:Nigerian Air Force)是否有能力阻斷空中航線。然封鎖措施最終仍有效實施,並伴隨內戰而持續兩年半的時長。由於當時尚未禁止利用飢餓作為戰爭手段(英语:Starvation (crime))[2] ,奈及利亞政府的封鎖行動亦無違反國際法[3],且所有中立國皆有義務遵守已宣布的封鎖令,奈及利亞並威脅將對無視封鎖的國家採取行動,同時也與喀麥隆達成協議,共同封鎖比亞法拉的陸地邊界。[3]期間曾有部分走私者試圖突破封鎖線,但有兩艘走私船隻遭到奈及利亞海軍擊毀。[4]
