Jakarta, Dec 22: Indonesian militant Abu Dujana, who is on trial in Jakarta on terrorism-related charges, has threatened that there are other militants and it is their obligation to carry out more attacks on Westerners in Indonesia, including Australian tourists in Bali.

The self-described military commander of the Jemaah Islamiah (JI) militant group, Dujana gave this chilling pre-Christmas message when asked if more terrorist attacks were being planned.

"There are other cadres out there … It is their obligation, " Dujana said.

And, if there was any lingering doubt, Dujana told the prosecutors that the controversial Muslim cleric Abu Bakar Bashir was the group's emir, or spiritual leader, for years.

Dujana has known Bashir since 1989, the year he went to train as a terrorist in Pakistan.

"Yes, he did say that Abu Bakar Bashir was the spiritual leader of JI, " a prosecutor, Totok Bambang, said.

Bashir, who was cleared by Indonesian courts of involvement with terrorists, continues to preach hatred throughout Indonesia and warned last week of a "disaster" if the three Bali bombers on death row were executed.

Dujana, a father of four, appeared this week in a South Jakarta court, where he faces a possible death sentence on multiple charges for supporting terrorism in Indonesia from early 2004 to June this year.

Dujana declined to answer when pressed on the whereabouts of his friend Noordin Mohammed Top, South-East Asia's most-wanted terrorist, or other Jemaah Islamiah members wanted over a series of bombings in Indonesia.

The arrest of Dujana and another Jemaah Islamiah leader known as Zarkasih in Central Java on June 9 was a crippling but not knockout blow for the group, which has not carried out a bombing since 2005, security analysts in Jakarta said.

Dujana had arranged for 200 kilograms of chlorate potassium, 12 kilograms of TNT and other explosive material to be sent to Islamic extremists in the Central Sulawesi town of Poso, where about 2000 people have been killed in religious fighting since 1999.

When Top and several other terrorists were on the run after masterminding bomb attacks, Dujana provided shelter and organised fake identity cards.

But after his arrest Dujana quickly abandoned any pretence at being an Islamic martyr and during interrogation in late June and August is said to have given investigators details about Jemaah Islamiah and its splinter groups.

Indonesian police, helped by Australian and US terrorism experts, have had recent success in capturing Jemaah Islamiah leaders, The Sydney Morning Herald reported.

Security analysts in Jakarta warn there are still dangerous terrorists at large, including Top and a bomb-making expert called Dulmatin.

Even though Australia and other countries continue to issue warnings about the threat of terrorism attacks in Indonesia, hotels in Bali are packed with tourists, and flights are fully booked for weeks. (ANI)
