SNIPPET: "SINGAPORE — Nur Azlin Mohamed Yasin spends several hours a day trawling the Internet, but she is not your typical young surfer, descending into a world of bomb-making, militancy and extremism. From her computer, she enters a world where young Muslims openly volunteer to fight against US-led coalition troops in Afghanistan or learn how to make explosives out of everyday materials. The 24-year-old Singaporean research analyst is constantly on the lookout for attack manuals, video clips of Islamist militants in training and fiery extremist chatter that could hint at an imminent assault somewhere."
