base, you could simply explain that there are bad people in the world everywhere, not only in Israel.(for parents, i think, this is perhaps the saddest realization you could get-- that your child will be growing up in a world so screwed and f up that humans are treated like s*t in some parts of the world) truly sad indeed. btw, base make sure you know the school of your child and its environment. it would help if you placed here in a tolerant environment.

mo lang!
