Police said an unexploded bomb left in a guestroom of the JW Marriott resembled devices used in 2002 attacks in Bali and one discovered in recent anti-JI raid on an Islamic boarding school.
National police spokesman Nanan Soekarna said, "They are from the same school. We found similar materials, similar tools, a similar method. That"s their job, that"s the same network, they are JI."
He also said, "Following the preliminary results of facial reconstruction, both suicide bombers are male. One of them has been identified. I cannot tell you his complete name but he has the initial 'N'. And another body is still in the process of identification."
Stephen Smith, Australian foreign minister on Sunday, Jul 19 visited the site of the attacks and advised the citizens to reconsider travelling the country.
