The Islamic State in Iraq and Syria (ISIS) terror group has proven itself adept at persuading impressionable youngsters to join its cause. Here are a few of the prominent ones:
SINGAPORE TERROR DUO
Two Singaporean youths were arrested in May for links to ISIS. The first, post-secondary student M. Arifil Azim Putra Norja'i, 19, had made plans to join ISIS in the Middle East, and if he was unable to join the terrorist group there, planned to strike here. The second radicalised Singaporean, a post-secondary youth, 17, who could not be named due to his age, was being investigated over the extent of his radicalisation.
BRITAIN'S YOUNGEST SUICIDE BOMBER
Talha Asmal became Britain's youngest suicide bomber at 17 when he detonated a vehicle filled with explosives in the Iraqi town of Baiji last month. He hailed from West Yorkshire, the same county as Habib Hussein - the 19-year-old who blew himself up on a bus in the July 7, 2005 attacks in London.
Three British schoolgirls - Amira Abase, 15, Shamima Begum, 15, and Kadiza Sultana, 16 - eluded an international search and intercept effort, to travel to Syria in February to become the brides of ISIS fighters. The students at Bethnal Green Academy in London travelled to Turkey before crossing the border into Syria. They were believed to be following in the footsteps of another classmate, who left to join ISIS a few months earlier.
ANZAC DAY TERROR PLOTTERS
Five teenagers in Australia and one in Britain were arrested in April over a planned terror attack on members of the police force during Anzac Day celebrations commemorating the first major military action fought by Australian and New Zealand forces during World War I.
One of them, Mehran Azami, 19, was found to have imported nearly 100 illegal weapons in preparation. Among the arrested were Harun Causevic, 18, and Sevdet Besim, also 18, who were friends of Abdul Numan Haider, a youth who was under investigation by an Australian terrorism task force and who was shot dead after he attacked a Melbourne police officer last year.
