An Indonesian court sentenced bombmaker Umar Patek to 20 years’ jail yesterday for his role in the 2002 Bali bombings, bringing to an end a 10-year probe into the nation’s deadliest act of terror.

Mr Patek, 45, was found guilty of six charges, a number of which related to the twin suicide bombings on a Bali nightclub and bar that killed 202 people, including 88 Australians.

“We sentence Umar Patek to 20 years in jail,” chief judge Encep Yuliardi told the West Jakarta district court.

Mr Patek was found guilty of premeditated murder linked to the Bali bombings, and other charges related to the Christmas Eve bombings in 2000 on several churches that killed 19 people in Jakarta.

Upon hearing his fate, Mr Patek stood up and shook the judges’ and prosecutors’ hands, before hugging his own lawyer and walking past reporters out of the court.

His lawyer Asludin Hatjani said that he would consult with Mr Patek and his family to discuss whether his client wanted to appeal.

“Umar Patek is very disappointed with the sentence and considers it too severe. He has been honest and admitted what he’s done, and he feels the court has not taken that into consideration.”

The decisions were made by a panel of five judges, who delivered their verdict after a gruelling 11-hour hearing observed by more than 100 journalists, many of whom were Australians, spilling out of the small courtroom.
