TEMPO Interactive, Jakarta:Convicted Bali Bombing terrorist, Hisham ibn Ali Zein alias Umar Patek, admitted to taking part in the assembly of explosives weighing 50 kilograms in 2002. However, to two Tempo journalists, Riky Ferdianto and Hermien Y. Kleden, he said that he was furious when he saw the bomb materials. "I was opposed to it right from the beginning," said Umar Patek. The member of Jemaah Islamiyah was angry when he saw his friend’s work room was filled with explosive bomb materials. Seeing them, he told his friend, "What are you thinking of? These are bombs. They’re not the same as bullets. Once detonated, all will be victims. Not just the foreigners." But his friend ignored Umar Patek, saying that everything had been discussed and the process had been started. “They told me, 'Stop it, you’re just small fry, and this cannot be undone," Patek said. In the terror act, he said, he was just a follower. His only expertise was to assemble bombs with low exploding power, which he learned in Afghanistan. In the Bali bombing, his task was to tape filing cabinet shelves. "The materials were of aluminum powder, easily scattered. So they had to be taped together," he said. Umar Patek regarded Bali Bombing I as a failed mission. The terror victims were not only foreigners who were regarded to be against Islam. They included many Balinese whose religion was Hindu, who were not at war with Islam. "So why fight against them?" he said. "If you want to wage a war, please go to Palestine." Due to his involvement in the crime that killed 202 people and injured 209, the West Jakarta District Court sentenced Umar Patek to 20 years in prison. The verdict was read out by presiding judge Encep Yuliardi on Thursday, June 21, 2012. CORNILA DESYANA
