1964 Ethiopian-Somali Border War

On 16 June 1963, Somali guerrillas started a minor insurgency at Hodayo, in eastern Ethiopia, a watering place north of Werder, after Ethiopian Emperor Haile Selassie rejected their demand for self-government in the Ogaden. The Somali government initially refused to support the guerrilla forces, which eventually numbered about 3,000. However, in January 1964, after Ethiopia sent reinforcements to the Ogaden, Somali forces launched ground and air attacks across the border and started providing assistance to the guerrillas however little to no advances were made and the war fissiled into a minor border conflict. The Ethiopian Air Force began punitive strikes across its southwestern frontier against Feerfeer, northeast of Beledweyne and Galkacyo. On 6 April 1964, Somalia and Ethiopia agreed to a cease-fire. At the end of the month, the two sides signed an accord in Khartoum, Sudan, agreeing to withdraw their troops from the border, cease hostile propaganda, and start peace negotiations.
