More than 20 people were killed in three days of clashes over land in western Ethiopia last week, police said on Saturday. Fighting over grazing and farm land is common in the south and west of the Horn of Africa nation. "A long-standing dispute over land along the border between Oromia and Benishangule states in western Ethiopia erupted into violence claiming the lives of more than 20 people from both sides last week," police spokesman Demsash Hailue told Reuters.
