Police in Indonesia say two men killed in a raid on Friday were brothers who were behind the attacks on two hotels in Jakarta in July.
The attacks on the Marriott and Ritz Carlton Hotels killed nine people including three Australians and a New Zealander.
The ABC reports the brothers were close associates of Noordin Mohammed Top, the man believed to have been behind the Bali bombing in 2002, who was killed last month.
One was known as the key recruiter of suicide bombers for Top.
Educated in Yemen, he can be heard in a video found on Top's computer inciting two suicide bombers to attack the hotels to help "destroy" America and Australia.
The ABC reports the identities of the two men were confirmed through fingerprints and DNA samples.
A total of 202 people died in the Bali bombings on 12 October, 2002.
The anniversary was marked on Monday by a gathering at at the Australian consulate in Bali.
Three men convicted of the bombings were executed by the Indonesian government last year.
