Although Singapore continued to remain safe from terrorist attacks in 2015, the country has not been completely immune from extremist and terrorist ideology. Since the rise of the Islamic State of Iraq and Greater Syria (ISIS), a handful of individuals from Singapore have travelled to Syria to participate in the conflict. In 2015, there were at least five cases of self-radicalised individuals who had plans to join ISIS, although authorities eventually disrupted their plans. Since 2014, there have been cases of Singaporeans travelling to participate in the conflict in the Middle East. Haja Fakkurudeen Usman Ali, a naturalised Singaporean citizen of Indian descent, had brought his wife and three children to Syria, with the hopes of joining the conflict. A 47- year-old female Singaporean is also believed to have gone to Syria with her Malaysian husband and two teenage children. Several others, including Abdul Basheer Abdul Kader, Zakaria Rosdan and Khairul Sofri Osman, had attempted to join the conflict in Syria but were stopped by authorities before they could leave.
