The three Bali bombers are spending their last hours of life in isolation lockdown in a remote Indonesian prison, with their executions to be meted out within days.

The deputy of Bali’s regional parliament, Igk Adhiputra, confirmed the three Islamic militants responsible for the 2002 Bali bombings should be executed within the next two days.

“All preparations for execution are under the prosecutor’s authority, but I admit that last night I got news that the three convicted, Amrozi and his friends, have been isolated,” Adhiputra said.

“It means that according to the death execution procedure, the executions should be three days after they were (first) isolated early Friday.”

Indonesian authorities have refused to give any details about the timing of the impending executions at Nusakambangan Island, off Central Java, other than that they will be held in “early November”.

French news agency AFP today quoted a prison source saying the three received formal notification of their executions at 9pm yesterday.

Death row prisoners receive notification 72 hours before they are executed, although there is no requirement to inform their lawyers or families.

One of their lawyers, Wirawan Adnan, has said he doesn’t expect to find out about the executions until after they have been carried out.

Indonesia’s Attorney-General’s Office today said news of the executions would be announced by the office in Jakarta, as the Bali prosecutors involved did not have authorisation to speak to the media.

“It is all from one door,” he said.

Security has been upgraded across Indonesia in anticipation of the executions of Mukhlas, his brother Amrozi, and Imam Samudra, with fears their deaths could spark a backlash from a small minority of hardliners.

The three men have publicly threatened their executions will be avenged.

Indonesian authorities said extra police had been stationed around Australia’s embassy in Jakarta, as well as the American and British missions.

Australian expat group ANZAS has cancelled its upcoming Melbourne Cup lunch in Jakarta for security considerations, its weekly newsletter says.

Police revealed yesterday they had found and defused two bombs in a Balinese Hindu migrant area on Sulawesi island on Wednesday and Thursday as tensions mount ahead of the imminent executions.

Meanwhile, the family of brothers Amrozi and Mukhlas say the executions are “good news” because they believe paradise awaits the pair after they die.

“The family don’t feel burdened by the execution. In fact, we’re happy because it means God and the prophet have given good news,” their older brother Muhammed Chozin told AFP in the bombers’ home village in East Java.

“If they die because they are standing up for the religion, they will be placed in paradise,” he said.

But Imam Samudra’s family in West Java said they would consider the executions as “an assassination not as a punishment” because they did not feel they were legitimate.

“Why we call it an assassination – if it was a punishment then all would run according to procedure,” Samudra’s brother Lulu Jamaludin told Indonesia’s TV One network.

“Until now I haven’t got the notification – it’s only rumours.”

He said many people had offered to donate their land for a burial site because they consider Samudra “a warrior”, but added: “We haven’t decided where to (bury him)”.
