The head of the United Nations' nuclear watchdog called on the US this evening to set an example to the rest of the world by cutting its nuclear arsenal and halting research programmes.
"The US government demands that other nations not possess nuclear weapons. Meanwhile, it is arming itself," Mr Mohamed ElBaradei, head of the International Atomic Energy Agency (IAEA), told Germany's Sternweekly.
Criticising President George W. Bush's plan for a national missile defence shield, he said: "Then a small number of privileged countries will be under a nuclear protective shield, with the rest of the world outside."
"In truth there are no good or bad nuclear weapons. If we do not stop applying double standards we will end up with more nuclear weapons. We are at a turning point," ElBaradei told the magazine in the interview released ahead of publication.
The IAEA director, who has overseen inspections of nuclear sites in Iraq, North Korea and Iran over the past year for half a decade said the world's five original nuclear powers - the US, Russia, Britain, France and China - should send a clear message to the world that they were disarming.
"Otherwise, we must live with the consequences. At the moment we are, at best acting, like the fire brigade. Today Iraq, tomorrow North Korea, the day after Iran. And then?" Mr ElBaradei said.
Under the terms of the 1968 nuclear Non-Proliferation Treaty (NPT), the global pact aimed at stopping the spread of atomic weapons, the five original nuclear powers were permitted to keep their nuclear arsenals but agreed to negotiate terms for full global disarmament in good faith.
Nuclear non-proliferation experts have complained that Washington is undermining the goal of global disarmament with statements about its interest in exploring smaller scale atomic weapons, like nuclear "bunker-busters".
