The Indonesian government has paroled one of the men who made bombs used in the deadly Bali attacks 20 years ago. But the controversial release has drawn criticism and concern.

Hisyam bin Alizein, known as Umar Patek, was a member of the Jemaah Islamiyah terrorist group, which was blamed for the bombings. After being captured in Pakistan in 2011, he had been sentenced to a 20-year prison term.

In 2002, massive explosions ripped through nightspots packed with tourists in the Kuta area, killing 202 people from 22 countries and territories.

Authorities have executed three of the masterminds, and some convicted group members remain in jail.

The Indonesian government released Patek halfway through his sentence, saying he is already deradicalized and shows complete loyalty to Indonesia. But it added that his release would be revoked should he violate any law again.

Patek's release is a very sensitive issue for the Australia government, which condemned the decision. Of the victims, 88 were Australian--the largest number of all the countries that lost nationals.

Australia's home affairs minister asserts that it is only the view of the Indonesian government that Patek has been rehabilitated.

Clare O'Neil remarked, "I think it is an absolutely horrible day for the victims and families of the Bali Bombings. We lost 88 Australians in the Bali Bombings, those people are never coming back."

The minister says she and the government deeply sympathize with families and communities who have lost loved ones.
