Rihanna [ tickets ] canceled a sold-out concert in Jakarta, Indonesia, due to security concerns, according to a Voice of America report. The pop star was scheduled to perform in the Indonesian capital Friday (11/14) in front of 6,000 fans.

Indonesian authorities reportedly have increased security across the country since last week's executions of three Islamic militants who were convicted of the 2002 Bali bombings, in which 202 people were killed. Supporters of the executed militants have threatened retaliatory attacks.
