UN powers say N. Korea, Iran 'serious' nuke threats
None
Ahead of a round of major nuclear talks, five major powers labeled North Korea and Iran as "serious challenges" to the world's nuclear security Friday, citing their repeated defiance of international obligations.
Senior diplomats with the UN Security Council's five permanent members singled out North Korea's nuclear test in February and Iran's "continued pursuit of certain nuclear activities" as among the biggest threats to the 1970 Nuclear Non-Proliferation Treaty, the world's most important pact on preventing the spread of nuclear arms.
