Three Indonesian men are possible suspects in the Bali bombings that killed nearly 200 people and sketches have been made of the three, according to the head of the international investigation into the blasts.
"There are three sketches of possible suspects. They are males and Indonesians," Made Mangku Pastika told reporters on Wednesday.
He stressed none of the three had been named as official suspects yet and he would not give their religions or further details "as it could mess up the investigation".
The sketches, based on witness statements, would only be used by investigators and not released to the public yet, he said.
Pastika declined to say whether Jemaah Islamiah might have been involved in the bombings that killed mostly foreigners drinking and dancing in clubs on Bali's Kuta Beach.
"There are several assumptions. One of them is related to a Muslim group, but that is only an assumption which must be matched with facts," he said.
Nevertheless, the screws were turning tighter on the militant Muslim Jemaah Islamiah as the United States said it would designate the Southeast Asian network a terrorist organisation and Indonesia said the Bali bombs bore the group's hallmark.
Indonesian police are still waiting to interrogate the group's alleged leader, militant cleric Abu Bakar Bashir, who was taken to hospital last week with what doctors say are respiratory, heart and ulcer problems.
Fellow Islamic teachers have been to see him in his hospital bed in the central Java city of Solo and quoted him as swearing in the name of Allah on Tuesday that he had nothing to do with an alleged plot to kill President Megawati Sukarnoputri.
