Indonesian authorities say they are delivering an execution order for the three men sentenced to death in the 2002 nightclub bombings on the resort island of Bali.
The announcement Saturday gave no specific time, but Indonesia typically gives condemned prisoners three days' notice of their executions. The Indonesian government will only say the execution is set for sometime in early November.
The three - Amrozi Nurhasyim, Ali Gufron and Imam Samudra - have been moved into isolation at Nusakambangan island prison, off the coast of Java. And a makeshift landing site has been set up in the hometown of two of the men where a helicopter might deliver their bodies.
The men will face a firing squad for planning the terrorist attacks on two nightclubs on Bali that killed 202 people, most of them Australian tourists.
The convicted bombers have warned that there will be retaliation by other Islamist militants if they are executed.
Australia has warned its citizens to avoid unnecessary travel to Indonesia because of what it says is a "very high risk of terrorist attack."
The suicide bombers who carried out the attacks were members of the regional terrorist group Jemaah Islamiyah.
Executions in Indonesia are typically carried out in the middle of the night without advance public notice.
