Paris - Up to 40 countries are believed to be capable of manufacturing nuclear weapons, underlining the need to reinforce and update the Nuclear Non-Proliferation Treaty, International Atomic Energy Agency chief Mohamed ElBaradei told a French newspaper.
The treaty, which came into force in 1970, has been overtaken by a world in which developing nuclear arms has become attractive not only to many countries, but also to "terrorist groups", ElBaradei told Friday's issue of Le Monde.
The number of countries believed to be able to create such weapons "is estimated at 35 or 40," he said.
"And under the current regime, there is nothing illicit for a non-nuclear state to conduct uranium-enriching activities ... or even to possess military-grade nuclear material," he said.
