Lassina Zerbo, the head of the UN’s Comprehensive Test Ban Treaty Organization called Iran to ratify the test ban treaty to prove that it is serious about not wanting to develop atomic arms, The Times of Israel reports.
"The CTBT bans nuclear explosions anywhere, and that’s already an assurance they could give to the international community that they are not in that process," said Zerbo.
According to him the ratification should be as a "follow-up to a deal."
