UN says it has new info on alleged Iran nuclear arms

VIENNA— The UN nuclear monitoring agency said Friday that "recently received" information is adding to concerns Iran may have worked on developing nuclear arms.
At the same time, a report by the organization — The International Atomic Energy Agency — noted that Tehran continues to stonewall its attempts to follow up on that information, which points to possible experiments with components of a nuclear arms program.
An annex to the confidential report listed "the outstanding issues which give rise to concern about possible military dimensions to Iran's nuclear programme." It included design work on a nuclear payload; experiments with explosives that could detonate such a payload and other work that could be linked to making weapons.
