At the final press conference of the summit on Wednesday, Col Gaddafi sought to back up his argument by citing other countries like Kenya, where elections in December 2007 were followed by ethnic killings, and war-torn Somalia. "We don't have any political structures [in Africa], our structures are social," Reuters news agency quotes him as saying. "Our parties are tribal parties - that is what has led to bloodshed." The Libyan leader's remarks could prove controversial in a continent where people have struggled for decades to have more open systems of government, says our correspondent.
