Incident Summary:

07/17/2009: On Friday at between 0745 and 0800 , in one of two related attacks, two suicide bombers detonated improvised explosive devices in the restaurants of two hotels, The Marriott and the Ritz Carlton, in Jakarta, Jakarta Raya, Indonesia. The blasts blew out windows and scattered debris and glass across the street, kicking up a thick plume of smoke. Facades of both hotels were reduced to twisted metal. Indonesian authorities say 9 people were killed and more than 50 wounded, seven of the wounded being U.S. citizens. A message was posted on two radical Muslim websites supposedly by wanted terrorist leader of Islamic group Jemaah Islamiah, Noordin Top, who said his group was behind the bombings. 'It is retribution for all the acts by the United States and its lackeys against Muslims and Muslim holy warriors,' said the statement written in Arabic and Bahasa Indonesia. It was signed off by Noordin Top, with the title of 'emir of Tandzim Al Qaeda Indonesia', a breakaway faction of the Jemaah Islamiah (JI) militant group. Amir Abdillah, 34, is the first to appear of a group of defendants believed to have taken orders from Noordin Mohammad Top.
