The man believed to head the regional terrorist group Jemaah Islamiya (JI) spent several months in Cambodia during 2002/3, government sources said. Hambali, whose real name is Riduan Isamuddin, spent at least two of those months in Phnom Penh at an Islamic guesthouse on Boeung Kak lake, a well-known backpacker area. JI is accused of carrying out numerous terrorist attacks in the region, including the Bali bombing that killed 202 people in October 2002. The guesthouse owner told the Post that Hambali, an Indonesian citizen, passed himself off as Thai, and was quiet, polite and had a penchant for current affairs. Hambali is being questioned by US authorities.
