SUDANESE authorities have reportedly released six political prisoners, with President Omar al-Bashir vowing to free all political detainees.

The six men walked free early on Tuesday to tearful relatives waiting outside Kober prison in Khartoum North.

Most of them are believed to have been held for more than two months in connection with a conference in Uganda, which led to a charter for toppling Bashir's 24-year-old regime using both armed and peaceful means.

Farouk Abu Issa, who heads the opposition alliance of more than 20 parties, could not be immediately reached for comment.
