"Amnesty International has urged African nations to arrest former US President George W. Bush during his visit to the continent this month.
"International law requires that there be no safe haven for those responsible for torture; Ethiopia, Tanzania and Zambia must seize this opportunity to fulfill their obligations and end the impunity George W. Bush has so far enjoyed," senior legal advisor for Amnesty International, Matt Pollard said.
According to the international rights group, African nations have the obligation to bring Bush to justice for his role in war crimes, Reuters reported.
This is while Bush's stay in Africa is aimed at raising awareness of cervical and breast cancers, as well as HIV/AIDS.
Last month, the Kuala Lumpur War Crimes Tribunal found Bush and former British Prime Minister Tony Blair guilty of committing crimes against humanity during the Iraq war.
Earlier this year, Bush canceled a trip to Switzerland due to fears of being arrested over allegations of ordering the torture of prisoners held in overseas military bases.
President from 2001 to 2009, Bush authorized the use of waterboarding, as well as other interrogation techniques, considered to be torture by human rights groups."
