KL nabs three ISIS fighters about to leave for Syria

Up to 1,000 recruits from Asia may have joined the group. Malaysia has arrested a total of 22 this year.

According to a US Admiral, the number could get larger going forward. Why are these people leaving their countries to join the ISIS? What drives them to take up arms for the ISIS cause? This is quite bewildering from an outsider's point of view.

Make no mistake, the ISIS does not tolerate criticism. This woman critical of ISIS has been executed. All she did was to criticise the ISIS group in social media.
