Three Indonesian Islamic militants on death row for the 2002 Bali bombings will be executed next month, prosecutors said Friday.

The convicts — Imam Samudra, Amrozi Nurhasyim and Ali Ghufron — have "exhausted their legal options," Jasman Panjaitan, a spokesman for Indonesia's Attorney General, told reporters.

The militants, who maintain their attacks were meant to punish the U.S. and its Western allies for alleged atrocities in Afghanistan, will be executed by a firing squad in the island prison where they are being held. Panjaitan did not provide an exact date.

They were convicted of planning and helping carry out the Oct. 12, 2002, suicide bombings targeting two nightclubs on the resort island of Bali that left 202 people dead, many of them foreign tourists.

Members of the government "don't have any hesitations" about having authorities carry out the death sentences, Vice President Jusuf Kalla told reporters after Muslim prayers.

Indonesia, the world's most populous Muslim majority nation, has won praise in recent years for rounding up hundreds of militants. It has been three years since a major attack.

On Tuesday, police detained five suspected militants said to have been plotting to blow up Indonesia's largest fuel depot in a north Jakarta neighborhood.

The Bali attacks — allegedly funded by al-Qaida — were carried out by members and associates of Jemaah Islamiyah, a Southeast Asian militant group blamed for at least three other suicide bombings in Indonesia, including attacks on the J.W. Marriott hotel and the Australian Embassy in Jakarta.

The last bombings occurred in 2005, killing 21 people in multiple blasts in Bali cafes and restaurants.
