Rihanna has canceled a concert scheduled Friday in Indonesia over security concerns.

Dive Purnomo, a spokeswoman for the event organizer, said the 20-year-old singer had been scheduled to perform before a sold-out crowd of 6,000 in the capital, Jakarta.

But she changed her mind while in Australia, one of several countries that issued a travel advisory to citizens in Indonesia after the weekend executions of three Islamic militants convicted in the 2002 Bali bombings.

The men called on followers to carry out revenge attacks if their deaths by firing squad went ahead.

Purnomo, of Show Master Live, said she hoped the "Umbrella" singer would come to Jakarta in January.
