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

Dive Purnomo, a spokes woman for the event organizer, says the pop 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.
