A young Indonesian militant trusted by al-Qaida is now in charge of Southeast Asia's regional terror group, Jema'ah Islamiyah, which remains dangerous despite more than 270 arrests since 2000, a top detective said Monday. Abu Dujana trained in Afghanistan with Hambali, a key regional militant now in US custody, and is known to be a "talented leader," according to Col. Petrus Reinhard Golose of Indonesia's counter terrorism task force. Golose said did not say when Dujana moved up through the ranks of Jema'ah Islamiyah, which is accused in a series of bloody bombings in Southeast Asia in recent years, including two strikes on Indonesia's resort island of Bali that killed more than 240 people, most of them foreign tourists. "Abu Dujana is the guy who leads," he said. "He has good relations with al-Qaida and is trusted." He did not elaborate.
