A Zimbabwean court freed on bail a man detained for insulting the president while testifying before a commission probing the fatal shooting of six civilians during post-election protests in August, lawyers said on Monday.Prosecutors said Wisdom Mkwananzi, 32, pointed at President Emmerson Mnangagwa's official portrait hung on the wall of a hall where the commission was hearing evidence from witnesses, and said: "I am an orphan because of this man. He killed my parents."He was accusing Mnangagwa of leading Gukurahundi, a government crackdown in the 1980s during which rights groups say at least 20 000 suspected government opponents were killed.Mkwananzi was released on $200 bail, according Kumbirai Mafunda, spokesperson for Zimbabwe Lawyers for Human Rights. "He was charged with undermining the authority of the president, assaulting police officers during his arrest and lying under oath," Mafunda told AFP.Mkwananzi is the latest person to be charged with insulting Mnangagwa.* Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
