JAKARTA (AFP) — Indonesian police Sunday confirmed regional terror outfit Jemaah Islamiyah as the culprits behind twin suicide blasts at Jakarta hotels, and said one of the bombers had been identified. Jemaah Islamiyah, which draws inspiration from al-Qaeda, has carried out dozens of bombings in Indonesia in the past decade including 2002 attacks in Bali that left more than 200 dead, mostly foreign tourists.

“We confirm that the attackers are from Jemaah Islamiyah because there are similarities in the bombs used,’’ national police spokesman Nanan Soekarna told a press conference.

He said an exploded bomb left in a guestroom of the JW Marriott, which was attacked along with the nearby Ritz-Carlton, resembled devices used in Bali and one discovered in a recent anti-JI raid on an Islamic boarding school. “They are from the same school. We found similar tools, similar materials and similar methods,’’ he said.

Police have identified one of the two suicide bombers who targeted the hotels during the breakfast period Friday when they were packed with foreign businessmen and diplomats, he said. “Following the preliminary results of facial reconstruction, both suicide bombers are male,’’ he said, quelling speculation that a woman was involved. “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.’’

Soekarna said nine people were killed in the attacks. Foreign Minister Hassan Wirayuda on Saturday put the toll at eight, including four foreigners and the two suicide bombers.

Three Australians and a New Zealander have been confirmed dead. The health ministry said a Singaporean man was also killed but did not give a complete name and the Singapore embassy here said it had not verified the death. An Indonesian man identified by the single name Darmanto was also among those killed, the health ministry said.

Soekarna has said 16 foreigners were injured, including six Americans, two Dutch, one Australian, two Canadians, one Indian, two South Koreans, one New Zealander, and a Norwegian.

Australian Foreign Minister Stephen Smith on Sunday visited the site of the attacks, as part of a trip to express solidarity with Australia’s northern neighbour.

Investigators say the bombers stayed in Room 1808 of the Marriott for two nights before the attacks and disguised themselves as guests when they walked into crowded dining and meeting areas and detonated their suitcase devices. The bombs — brought into the hotels despite airport-style security measures — were packed with metal nuts to maximize the carnage.

The Indonesian security ministry’s anti-terror desk chief, Ansyaad Mbai, has said that evidence pointed to Malaysian-born extremist Noordin Mohammed Top, who leads a violent splinter faction of JI. Noordin is accused of masterminding bombings at the Jakarta Marriott in 2003, the Australian embassy in 2004 and Bali restaurants in 2005 which have killed more than 40 people.
