Meanwhile, Iran says it might reconsider its cooperation with the UN nuclear watchdog, should the 2015 deal with the US falls through. The country's nuclear chief, Ali Akbar Salehi, was quoted as telling IAEA Director General Yukiya Amano in a phone call, that Tehran would take decisions that might affect its current cooperation with the IAEA, should the US fail to meet its commitment in the 2015 deal. US President Donald Trump faces a mid-January deadline to decide whether or not to renew temporary waivers for US sanctions against Iran. In October, Trump refused to certify that Iran was complying with the deal.
