FORMER US President Bill Clinton arrived in Nigeria late on Wednesday ahead of a two-day regional summit on HIV/AIDS, airport sources said. UN Secretary General Kofi Annan arrived in the Nigerian capital a little earlier for the two-day summit, on Aids, tuberculosis and other infectious diseases, involving nearly 50 African heads of state. Clinton was due to address the leaders at the summit’s opening ceremony on Thursday. Among the African heads of states who also turned up on Wednesday were Ghana’s John Kufuor, Libyan leader Moamer Kadhafi, Sam Nujoma of Namibia and Rwanda’s Paul Kagame. – AFP
