Zimbabwe opposition leader to return for election runoff

Mugabe, 84, has ruled Zimbabwe since independence in 1980 and once was hailed for promoting racial reconciliation and bringing education and health care to the black majority. But in recent years he has been accused of holding onto power through elections that independent observers say were marred by fraud, intimidation and rigging, and of overseeing his country's economic collapse.

"Mugabe was once my hero, too," Tsvangirai said Saturday. "It is very, very sad for me to call Mugabe a former liberator. It is sad for me to say that he has turned his back on both his people and his continent."
