JAKARTA, Indonesia — Indonesian prosecutors on Thursday demanded the death sentence for an Islamic militant charged with helping plan the 2004 Australian Embassy bombing in Jakarta that killed 11 people.

Iwan Darmawan, also known as Rois, is accused of buying a van and materials for explosives used in the attack. The 30-year-old clothing salesman is also accused of hiding some of the key suspects.

Authorities say Rois took his orders from Azahari bin Husin, a leader with the regional terror group Jemaah Islamiyah whom police believe was the mastermind of the attack. He remains at large in Indonesia.

Rois, who attended a militant training camp in the Philippines in the 1990s, acknowledged buying the materials, but insisted he did not know they would be used for the bombing. He has maintained his innocence.

"We've demanded that the defendant Rois be sentenced to death," said Nendra, a state prosecutor, who goes by only one name.

"The fact is that Rois is guilty of helping plan the attack as well as hiding the key suspects," Nendra said. "During the trial, he never expressed regret about what he had done. His actions caused the death of innocent people and threatened national stability."

Rois, wearing a skull cap and traditional Islamic shirt, appeared to be shocked and on the verge of tears as the sentence request was read. He later told reporters that he was innocent.

"The allegations against me are untrue and based on something I've never done," he said.

Two of the six Australian Embassy bombing suspects have already been sentenced to 3 1/2 years and 4 1/2 years on charges relating to the Sept. 9, 2004 blast.

A fourth suspect, Heri Sigu, is on trial for allegedly helping hide some of the key suspects. Prosecutors on Thursday demanded a seven-year jail term for Sigu, who has denied involvement in the bombing.

"All the evidence presented in my defense has been useless. The trial has been designed to find me guilty," said Sigu.

Police blamed the attack on Jemaah Islamiyah, which has also been linked to the 2002 Bali bombings that killed 202 people and a 2003 blast at Jakarta's J.W. Marriott hotel that killed 12 people.
