"Political violence must end today. We can no longer afford brother against brother, because one happened to have a different political opinion," Tsvangirai said to cheers from thousands of supporters at the Glamis stadium in the capital, Harare.
"I can assure that the culture of impunity and of violation of human rights must end, and it must end today," he added.
Tsvangirai vowed to secure the release of political prisoners, amid international calls for freedom for about 30 activists who were abducted by security forces and detained in secret last year.
"It hurts that as we celebrate here today there are some who are in prison. I can assure you that they are not going to remain in those dungeons any day or any week longer," he said. – AFP
