Amnesty is only addressing looting, burning, and attacks on civilians in that sentance. They do not say that these things were the cause of the destruction in the satellite images. Amnesty has not made any claims about who is responsible for that destruction. They are saying that they are investigating.

The only one (besides Georgia and Russia) who is making claims about who is responsible, is the person in this thread who is arguing with me. Amnesty has made no such claims.
