This is a terrorist attack, but the odds are that Muslims aren't involved. For starters, there aren't that many Muslims in Sri Lanka. That island nation, off India's coast, is about
- 69.1% Buddhist
- 7.6% Muslim
- 7.1% Hindu
- 6.2% Christian
- 10% something else.
The Sri Lankan Tamil people are about 80% Hindu. 90% of Indian Tamils are Hindus. So, if there is any religious component in the Tamil rebels' motives, it's probably inspired by Hindi beliefs.
Not all terrorists are Muslims. And, terrorism is a global problem: not limited to the Middle East, Europe, and America.
