The Associated Press has reported that pop star Rihanna canceled a sold-out concert scheduled in Indonesia over security matters. The singer was set to sing tunes from her latest album in front of a crowd of some 6,000 fans, but changed her mind while performing in Australia. Officials have cautioned citizens in Indonesia after the weekend executions of three Islamic militants convicted in 2002 of bombings in Bali. It's reported that before they were executed, the men called on their followers to carry out revenge attacks. Seems like "RiRi" made the right choice after all.
