Iranian Foreign Minister Javad Zarif, in response to Netanyahu's speech at the United Nations General Assembly, in a Tweet on Friday morning called out Israel for having the only 'secret and 'undeclared' nuclear weapons program. 'No arts & craft show will ever obfuscate that Israel is only regime in our region with a *secret* and *undeclared* nuclear weapons program - including an *actual atomic arsenal*. Time for Israel to fess up and open its illegal nuclear weapons program to international inspectors,' he wrote on Twitter.
