I hear knowledge that Al Qaeda operatives have frequented Thailand. Now they are Isis. Let me explain what a Wahhabi sect Sunni believes, so you will see the big picture. ANYBODY THAT DOESN’T BELIEVE THEIR BS ——DIES! Even Shiite Islamist. What do you think they want to do to Buddhists?
Thailand has a domestic jihad going on in the far south of the country bordering Malaysia where Muslim live. This bombing is probably related to that.
