Russia hosts a conference at a time of global unease about atomic ambitions in Iran and North Korea.
Delegates from more than 40 countries are in Russia, as concerns grow about the threat of nuclear war.

Russia’s foreign minister opened the conference in Moscow by saying Iran’s latest move does not pose a threat to non-proliferation.
There are an estimated 14,500 nuclear weapons around the world, in the hands of nine countries.
Five have signed on to the United Nations’ non-proliferation treaty – the US, United Kingdom, France, Russia and China.
