Two Islamic militants jailed for the Bali bombings that killed 202 people will be freed Tuesday and 10 others will have their sentences reduced to mark the end of the Islamic fasting month, officials said.

Indonesia traditionally marks national holidays by cutting prison terms for inmates who exhibit good behavior, usually by several months. But the decision is likely to anger countries that lost citizens in the 2002 attacks on two crowded nightclubs.

Eighty-eight of those killed were Australians.

Sirojul Munir, sentenced to five years for hiding one of the masterminds of the bombings, will leave the jail in East Kalimantan's capital of Balikpapan on Tuesday, said Edi, a prison official who uses a single name.

The other militant, whose identity was not released, will be released from the main prison on Bali island, said Anak Agung Mayun Mataram, the justice ministry's head of Bali's prison division.

A total of 33 people were jailed over the 2002 Bali blasts, the most deadly in a string of attacks in Indonesia blamed on the Al Qaeda-linked militant group Jemaah Islamiyah.

Three -- Amrozi, Ali Gufron and Imam Samudra -- are scheduled to be executed and three others are serving life sentences. Under Indonesian law, they are not eligible for prison sentence reductions.
