Two days after terror returned to Indonesia’s capital, police have confirmed Friday’s deadly attacks bear all the hallmarks of Jemaah Islamiah.A breakaway faction of the militant group has been widely blamed for the carnage at two luxury hotels where tributes have been paid to the nine dead and dozens wounded. Suicide bombers struck at breakfast-time at the JW Marriott and Ritz-Carlton hotels, in an upmarket business district of Jakarta. Foreigners account for many of the casualties. At a news conference today, police said the attackers used the same explosives as those used in bombings on Bali. They were also identical, they said, to explosive material found recently in Java, at a house linked to Malaysian extremist Noordin Mohamed Top. He is thought to lead a splinter faction of Jemaah Islamiah. Co-founded in 1993 by Indonesian cleric Abu Bakar Bashir, its goal is the creation of an Islamic “super-state” spanning several countries in the region. Noordin Mohamed Top is wanted in connection with bombings on Bali in 2005 and 2002, when more than 200 people wre killed, many of them foreign tourists.
