On 13 September 2000, a car bomb detonated in the basement of the Jakarta Stock Exchange building in Jakarta, Indonesia. The explosion set off a chain of further explosions as multiple vehicles caught fire in the basement levels. Most of those killed were drivers who had been waiting near their employers' cars; many took shelter inside their vehicles but suffocated as thick black smoke filled the enclosed basement area.
The attack caused significant disruption beyond the immediate casualties. Trading on the Jakarta Stock Exchange was suspended for two days following the bombing, and the Indonesian rupiah experienced a sudden, brief devaluation in the aftermath.
Responsibility for the bombing was later claimed by Jemaah Islamiyah, a Southeast Asian Islamic extremist group with documented links to al-Qaeda. The group was also linked to other attacks in the region during this period, including a bombing at the Philippine consulate in Jakarta that had occurred approximately a month before the stock exchange attack, and the 2002 Bali bombings.
The investigation into the Jakarta Stock Exchange bombing led to convictions distinct from the later Jemaah Islamiyah claim of responsibility. In August 2001, an Indonesian court sentenced two men to 20-year prison terms for masterminding the attack. Both men, Teuku Ismuhadi Jafar and Nuryadin, were members of Kopassus, Indonesia's special forces unit. Prosecutors had sought the death penalty for Jafar and life imprisonment for Nuryadin. Nuryadin escaped from detention in July 2001 and was subsequently tried and sentenced in absentia by the South Jakarta Court. The court declined to impose the death sentence on Jafar, reasoning that although he had ordered the bombing, he had not personally participated at the scene of the attack in downtown Jakarta.
The case illustrates overlapping claims of responsibility and adjudicated findings: while a militant group publicly claimed the attack, the judicial process that produced convictions centered on individuals connected to the state's special forces apparatus. Whether the convicted individuals acted in connection with Jemaah Islamiyah or independently is unclear.
