JAKARTA, INDONESIA - At least nine people were killed and more than 40 injured, many of them foreigners, on Friday when bombs exploded at two luxury hotels in the Indonesian capital Jakarta, officials said.
Police said it was too soon to say who might have been responsible, but Islamic militant network Jemaah Islamiyah (JI) has been blamed for a string of suicide attacks on local and Western targets in Southeast Asia in recent years.
The bombings were the first major attack in Indonesia since a series of suicide bombings on the resort island of Bali in 2005 blamed on JI. Here is a chronology of key attacks in Indonesia since 2000, and events in JI's history:
1993: Indonesian cleric Abu Bakar Bashir and Abdullah Sungkar found JI while in exile in Malaysia from dictator Suharto's regime.
December 24, 2000: Improvised bombs disguised as Christmas gifts delivered to churches and clergymen kill 19 people and injure scores more across Indonesia.
December 30, 2000: Twenty-two people killed in a series of bombings in the Philippines blamed on Al-Qaeda-trained bomb expert Fathur Rahman al-Ghozi, alias Randy Ali.
June 2001: Mohammed Iqbal bin Abdurraham, aka Abu Jibril, arrested in Malaysia. US State Department freezes his assets two years later, saying he had been JI's "primary recruiter and second-in-command."
January 15, 2002: Al-Ghozi arrested in the Philippines. He escapes in July 2003 and is killed in a shootout with police three months later.
October 12, 2002: Bombs at crowded nightspots in the resort island of Bali kill 202 people, mostly foreign tourists.
Three men - Amrozi, Mukhlas and Imam Samudra - are convicted of carrying out the bombings and sentenced to death but the suspected mastermind, Malaysian Noordin Mohammad Top, is at large.
August 5, 2003: A car bomb tears through the JW Marriott hotel in Jakarta, killing 12 people and wounding 149 others.
August 11, 2003: Key JI leader Hambali, accused among other things of plotting to blow up US airliners, is captured in Thailand and handed over to US custody.
September 9, 2004: A suicide car bomb kills 10 outside the Australian embassy in Jakarta.
March 3, 2005: Bashir is sentenced to two-and-a-half years in prison after being found guilty of a "sinister conspiracy against the state." He is released in June 2006 and his conviction is later overturned on appeal.
May 28, 2005: Twin bomb blasts kill 22 in a market in the Central Sulawesi town of Tentena in an attack bearing the hallmarks of JI.
The bombings come as JI moves to provoke a "holy war" between Muslims and Christians amid a local sectarian conflict that claims around 1,000 lives.
October 1, 2005: Three suicide bombers detonate explosives at tourist spots on Bali, killing 20.
Police track down alleged bomb-maker Azahari Husin, a compatriot and ally of Noordin, and kill him in a volley of gunfire on November 9 on Java island.
June 9, 2007: Police arrest self-proclaimed JI leaders Zarkasi and Abu Dujana in Java. Both men are sentenced to 15 years in prison in April 2008.
June 28-July 2, 2008: Police round up 10 members of an alleged cell linked to Noordin in South Sumatra.
November 9, 2008: Bali bombers Amrozi, Mukhlas and Imam Samudra are executed by firing squad.
July 17, 2009: At least nine people are killed and 41 injured, many of them foreigners, when bombs exploded in the Ritz-Carlton and JW Marriott hotels in Jakarta. Police said it was too soon to say who might have been responsible. A third explosion was reported near a shopping complex several hours later, but police later denied that it was also caused by a bomb.
