Three Indonesian Muslim militants on death row for the 2002 Bali bombings plan to launch yet another appeal to have their death sentences overturned, an attorney for the condemned men said Thursday.

The three militants - Imam Samudra; Mukhlas, alias Ali Ghufron; and Amrozi - face the firing squad for their roles in the bombings of two nightspots on the popular tourist island that killed 202 people, mostly foreign tourists.

Lawyer Achmad Kholid said another judicial review appeal would be filed on behalf of the three men's families.

"We will submit it immediately, hopefully next week," the state-run Antara news agency quoted Kholid as saying.

The lawyer made the statement when accompanying Mukhlas' family to visit him in prison on Nusakambangan Island off the southern coast of Central Java.

It was the latest in a string of judicial reviews aimed at delaying the execution of the three men, who have been on death row since 2003.

Government authorities previously said the three could be executed because they have exhausted all their legal options after the Supreme Court in July turned down the third appeal for a review.

The attorney general's office was scheduled to announce Friday when the executions would take place. Prosecutors have expected the death sentence to be carried out by the end of the year.

Indonesia's Constitutional Court on Tuesday rejected arguments by the three men's attorneys that executions by firing squad were cruel and inhumane. The court argued that the alternatives also were painful.

Imam Samudra, Mukhlas and the so-called smiling assassin Amrozi were alleged members of Jemaah Islamiyah (JI), a regional terrorist network responsible for several bombings across Indonesia in recent years, including several simultaneous church bombings across Indonesia on Christmas Eve 2000, bombings on Bali in 2002 and
2005, the bombing of a JW Marriott hotel in Jakarta in 2004 and an attack on the Australian embassy in 2005.

None of the bombers have shown remorse over the attacks.
