On 1 October 2005, suicide bombings occurred on the island of Bali. The attacks bore the hallmarks of the militant Islamic group Jemaah Islamiyah (JI)—a group linked to Al-Qaeda—though police investigation was underway. The group was also responsible for the 2002 Bali bombings. SBY condemned the attack, promising to "hunt down the perpetrators and bring them to justice.".
