On 26 September 1976, on the eve of Meskel, the Tigrayan People's Liberation Front turned back an advance by an armed detachment of 250 Ethiopian Democratic Union fighters at Chiameskebet, a village near Shiraro, on 26 September 1976, forcing them to retreat across the Tekezé. Both sides suffered heavy casualties; amongst the TPLF wounded was their general, Mehari Tekle, who was fatally wounded in the battle and died a few days later. Flooding by the Tekezé in August 2006 damaged 68.5 hectares planted in fruits and vegetables and buried 21 water pumps. A violent storm in the second week of the same month also damaged 48.5 hectares of crops.
