Supporters of Malaysia's opposition parties scuffle with police as they try to deliver a "Happy Birthday Altantuya" cake to the Prime Minister's Office in Putrajaya, May 6, 2009. Malaysia's Prime Minister Najib Razak has been mauled on opposition-supporting internet sites that have linked him to the lurid murder of a Mongolian model, Altantuya Shaaribuu, although there has been no evidence and Najib has repeatedly denied involvement.
