12 October 2002: A bomb explodes in a Bali nightclub killing 202 people, many of them Westerners.
Islamic group Jemaah Islamiah (JI) is blamed for the blasts. In the months following the attacks about 30 alleged JI members are arrested and put on trial.
In October 2003, Mukhlas, also known as Ali Gufron, described by prosecutors as the co-ordinator of the bombings, was sentenced to death by an Indonesian court.
While the precise nature of JI's relationship with al-Qaeda is not known, many analysts believe informal links between the two organisations have grown in recent years.
