Hello codeforces!

As you may know, this year, the IOI onsite round will be held in Tehran as said in http://ioi2017.org/! and also you may heard that neither Israeli passport holders nor Iranian passport holders are allowed to enter the other country (no visa is issued!). so what will happen? Would Israel participate remotely or it won't participate at all?
