Background information

(The following account of the 2002 Bali bombings draws heavily on a wikipedia entry which can be read in full at http://en.wikipedia.org/wiki/2002_Bali_bombings)

The 2002 Bali bombings occurred on 12 October in the tourist district of Kuta on the Indonesian island of Bali. The attack was the deadliest act of terrorism in the history of Indonesia, killing 202 people, 164 of whom were foreign nationals (including 88 Australians), and 38 Indonesian citizens. A further 209 people were injured.
The attack involved the detonation of three bombs: a backpack-mounted device carried by a suicide bomber; a large car bomb, both of which were detonated in or near popular nightclubs in Kuta; and a third much smaller device detonated outside the United States consulate in Denpasar, causing only minor damage.
Various members of Jemaah Islamiyah, a violent Islamist group, were convicted in relation to the bombings, including three individuals, Imam Samudra, Amrozi Nurhasyim and Mukhlas Ghufron, who were sentenced to death.
Abu Bakar Bashir, the alleged spiritual leader of Jemaah Islamiyah, was found guilty and sentenced to two and a half years imprisonment.
Riduan Isamuddin, generally known as Hambali and the suspected former operational leader of Jemaah Islamiyah, is in United States custody in an undisclosed location, and has not been charged in relation to the bombing or any other crime.
