What's funny is that originally the "terrorists" issued a statement saying they thought they were shooting at a Ukranian fighter jet. Then they quickly retracted that statement and said they don't possess the weapons to shoot an airliner down. Even though they've been shooting down Ukranian planes for a few weeks now. I think it's obvious what happened.
There were reportedly 23 US citizens on board the plane, so things might get interesting. Especially since Russia gave them the weapon. You have to have something military grade to shoot down a plane moving at 500+MPH at 33,000 feet.
