Now this is the exact reason, India is behind this attack, India decided not to visit Pakistan and tried to pressurized Srilanka to follow the suit, but, when Srilankan decided to carry on, this is how Indian reacted... if the world have to live in peace, somebody have to teach India a good lesson.
Conspiracy theories aside do you have an iota of proof that any Indians are involved. It is easy to be carried away by rhetoric. Let there be a full fledged investigation and then make such scathing attacks.
