The government has confirmed that after the attack on Dangote's business concerns on Monday, 10 other businesses have been burnt down and looted in the Oromia region. The government blames the violence on organized criminals.
The Information Minister Getachew Reda said, the motorbike riding criminal gangs involved in the violence used petrol bombs to attack their targets.
Trucks and machinery belonging to the Dangote group - owned by Africa's richest man, Aliko Dangote - were burned by protesters in restive region following a deadly stampede at a festival last Sunday.
The government has repeatedly denied claims by the opposition that the security forces were to blame for the panic that resulted in the stampede. Official figures indicate that 55 people died.
Among the thousands of festival participants, a number of them marched chanting anti-government slogans and their arms crossed above their heads.
The Oromia region lies south of the Ethiopian capital Addis Ababa and is the center of the Oromia protests last year which Human Rights Watch reported that over 400 protesters were killed.
