Oct. 24 (Bloomberg) -- Indonesia will execute the three Bali bombers early next month, six years after 202 people were killed in the Southeast Asian nation's worst terrorist attack.

The three terrorists, Amrozi, Imam Samudra and Ali Ghufron, who have been on death row since their conviction five years ago, will be executed in the Nusakambangan prison where they are jailed, said Jasman Panjaitan, spokesman for the Attorney General. He didn't give an exact date for the execution.

``All the matters relating to legal procedures have been completed,'' Panjaitan told reporters in Jakarta today. ``The decision is final.''

Indonesia, which has been hit by bombings annually from 1999 to 2005, increased security across the world's largest archipelago ahead of the expected execution. Police earlier this week foiled a plot to bomb a fuel depot in Jakarta and arrested five suspects. Indonesia, home to the world's largest Muslim population, and Australia, which lost 88 of its citizens in the 2002 Bali bombings, blamed the attacks on Jemaah Islamiyah.

Jemaah Islamiyah, which is linked to al-Qaeda and wants to turn Indonesia into an Islamic state, is also blamed for a Marriott Hotel bombing in Jakarta in 2003 that killed 12 people, a bomb explosion outside the Australian Embassy in Jakarta in 2004 that killed at least nine, and a second attack in Bali in 2005, when three suicide bombers killed themselves and 20 other people.

Beheading Rejected

Indonesia's constitutional court earlier this week rejected a claim by the three convicted men that the execution by firing squad would violate the constitution and dismissed their request to be beheaded, the Associated Press said.

``There is no method of execution without pain,'' AP cited Presiding Judge Mohammad Mahfud as saying on Oct. 21.

Their execution by firing squad had earlier been planned to take place before the Muslim fasting month of Ramadan that started on Sept. 1.

The Attorney General's office has to notify the lawyers and the families about the execution date three days before it takes place, said Wirawan Adnan, a lawyer for the convicted men.

``We haven't received any notifications yet,'' he said.

Some U.K. relatives of those killed in the bombings said the executions may be counter-productive.

``These men will be seen as martyrs by many of their sympathizers and thus their execution will be a propaganda coup for the Jihadist cause,'' the U.K. Bali Bombing Victims' Group said in an e-mailed statement. ``These men are mass murderers not martyrs, and we ask the world to see them as that.''
