TO GO WITH AFP STORY BY CHRIS STEIN (FILES) A file photo taken on March 4, 2013 shows Ghanaian Cardinal Peter Kodwo Appiah Turkson arriving for talks ahead of a conclave to elect a new pope at the Vatican. Turkson, one of Africa's two candidates considered eligible to become the next pope, has earned respect as a peacemaker at home, but faced criticism abroad over a controversial video. The 64-year-old cardinal and head of the Vatican's Pontifical Council for Justice and Peace is considered progressive by some supporters, and his mediation during a tight Ghanaian election in 2008 has won him high praise. Turkson is one of two Africans considered eligible to replace retiring Pope Benedict XVI, alongside South African Wilfrid Napier. AFP PHOTO / VINCENZO PINTO
