What does Saudi have to do with the topic? Or is pointing fingers at others a way of defending Iran which was mentioned because of its direct political involvement, not them being Shia? Anyway, burning banks is stupid and not a solution to anything. Islam includes but certainly isnt limited to hudood and banning this or that. Thats why theres much research being done on Islamic economics, and more and more banks are adapting everyday. Thats a more civilized smarter approach.
