Arab League Secretary General Amr Mussa has called for all Middle East leaders to commit their nations to a nuclear-free future.
"Security in the Middle East depends on an agreement among all members of that region to build a zone free of WMD [weapons of mass destruction], nuclear weapons, as well as other types of those destructive weapons," Mr Mussa said during a visit to Madrid.
"If there is an exception to the rule, the whole work would be useless. All countries should adhere to the NPT [Nuclear Non-Proliferation Treaty] and the only country in the region that has not joined is Israel.
"All countries should commit themselves not to develop nuclear weapons. All countries with no exception should be party to this," he insisted.
"If one country is allowed to have those weapons . . . it won't work, because we feel threatened by all WMD coming from whatever direction. We find no reason, no logic, for us to accept that all countries join the NPT with the exception of one," Mr Mussa said.
