JAKARTA (AFP) - The alleged mastermind behind the 2002 Bali bombings that killed more than 200 people gave gun training to militants at a camp in Aceh on Sumatra island, police said Wednesday. Police made a connection between Umar Patek and the camp, which was discovered last year, when the suspect on Wednesday retraced his steps in plotting terrorist acts in several locations in Jakarta. "After the Bali bombings, Umar Patek travelled to many places. He returned to Indonesia and participated in militant training in Aceh," National Police spokesman Saud Usman Nasution said. Police believe militants at the Aceh camp were planning Mumbai-style attacks on Westerners, and plotting the assassination of Indonesian politicians.
