Police in Indonesia are working to confirm if a man killed in a raid in central Java on Saturday was Indonesia's most wanted terror suspect, Noordin Mohammed Top.
Anti-terrorism police were acting on information that Noordin Top was using the house in Temanggung as a refuge, but the ABC says there are now reports that their intelligence may have been wrong.
Police stormed the premises at 0945 (0245 GMT) on Saturday after a 17-hour siege.
Police say DNA tests will be carried out but will take at least a week.
Noordin Top is suspected of involvement in all major attacks carried out recently in Indonesia: including the bombings of two hotels in Jakarta on 17 July that killed nine people and also the 2002 Bali bombings which killed 202 people.
He is also wanted over suicide attacks on the JW Marriott hotel in Jakarta in 2003; a raid on the Australian embassy in the capital in 2004; and the second Bali bombing in 2005.
Australian Prime Minister Kevin Rudd says it's still unclear as to who precisely has been killed and who has been apprehended.
He intends to speak with President Susilo Bambang Yudhoyono on Sunday to obtain the latest developments.
