Indonesia's most wanted Islamist militant, Noordin Mohammad Top, was killed in a police shoot-out in Central Java, police said on Thursday, lifting a major security threat ahead of a planned visit by U.S. President Barack Obama.
Malaysian-born Top, who set up a violent splinter group of regional militant network Jemaah Islamiah, was widely considered the mastermind of the bomb attacks on two luxury hotels in Jakarta in July, as well as other attacks in Bali and in Jakarta, which have killed scores of Westerners and Indonesians.
Here is a timeline tracing major attacks and plots that have been blamed on Jemaah Islamiah since its formation.
1993 - Indonesian cleric Abu Bakar Bashir and Abdullah Sungkar found Jemaah Islamiah while in Malaysia. The two return to Indonesia after the fall of President Suharto in 1998.
1995 - Jemaah Islamiah operational chief Hambali is thought to be involved in a Jemaah Islamiah plot to bomb 11 U.S. commercial airliners in Asia, the U.S. State Department says in 2003.
Dec 30, 2000 - Five blasts in Manila kill 22 people. In 2009, three members of Philippines militant group the Moro Islamic Liberation Front (MILF) are sentenced to life imprisonment for the multiple bombings, said to have been carried out under instructions and with funding from Jemaah Islamiah leaders.
Dec 24, 2000 - Series of Christmas Eve blasts at Jakarta churches and elsewhere in the country kill 17 people and wound about 100. At first thought by some to have political motivations, these blasts are later tied to Jemaah Islamiah.
Dec 2001 - A Jemaah Islamiah plan to attack diplomatic missions including the U.S., Israeli and British embassies, is foiled by authorities in Singapore and more than a dozen suspected militants are arrested.
Oct 12, 2002 - Blasts on the tourist island of Bali kill 202 people, many of them foreign tourists, including 88 Australians. Jemaah Islamiah is blamed. The United States designates the group as a foreign terrorist organization after the blasts. Three Jemaah Islamiah-linked militants are executed for the attacks in November 2008.
March 2003 - Two blasts at the airport and a ferry pier in Davao, a southern port city in the Philippines, strike weeks apart, killing 38 people in total. Jemaah Islamiah-linked militants are blamed.
Aug 5, 2003 - Bomb outside JW Marriott Hotel in Jakarta kills 12 people, including a Dutchman, and wounds 150. Jemaah Islamiah is blamed.
Sept 9, 2004 - A powerful bomb explodes near the Australian embassy in central Jakarta killing 10 Indonesians and wounding more than 100. The al Qaeda-linked Jemaah Islamiah is blamed for the attack.
Oct 2, 2005 - Suicide bombers linked to the militant Jemaah Islamiah network set off three blasts on the resort island of Bali that killed 23 people, including the three bombers and some foreign tourists. More than 100 people were wounded.
July 17, 2009 - Bomb blasts rip through the JW Marriott and the Ritz-Carlton hotels in Jakarta's business district, killing nine people and wounding dozens in an attack analysts say could signal a resurgence of activity from Jemaah Islamiah.
