Fahmy mentioned Israel in particular in his call for Mideast countries to declare their support for a region "free from weapons of mass destruction, as well as from nuclear, chemical and biological weapons," Egyptian newspaper al-Youm Al-Sabe'a wrote on Saturday.
The Non-Aligned Movement (NAM) also has recently invoked major concerns over the Israeli regime’s undeclared nuclear weaponry, stressing they embody the highest threat to Middle East peace and security.
The interim foreign minister also told the UN General Assembly in New York that Egypt's latest political transition, including presidential and parliamentary elections, will end "by next spring."
Fahmy is part of an interim government installed by the country's powerful military after the ouster of former Islamist president Mohammed Morsi in July.
Earlier this week, Fahmy said Egypt's relations with the United States are "unsettled" as the country struggles to redefine its national interests.
