Ethiopia is to drop charges against 528 prisoners in the coming days.
Attorney general Getachew Ambaye said they would be released from jail after two days of what he described as rehabilitation training.
He said prisoners due for release included those who had not used force to try to dismantle the government.
Earlier this month, Ethiopia said it would release some of the country’s politicians and close a notorious detention centre.
Thousands of people have been detained during more than two years of anti-government protests.
