Factories destroyed in Ethiopia's Oromia region Factories are burned to the ground in Dera, a town in Ethiopia's Oromia region, in a spate of violent protests against the government. The town is home to one of Ethiopia's largest ethnic groups who along with the Amhara have waged nearly a year of protests against a government largely made up of minority Tigrayans. The violence has led to over 1,500 arrests since a state of emergency was declared two weeks ago. IMAGES.
