Iran triples stockpile of enriched uranium in breach of nuclear deal

Watchdog says country may also be storing material at three undeclared sites

Iran has nearly tripled its stockpile of enriched uranium since November in violation of its deal with world powers and is refusing to answer questions about three possible undeclared nuclear sites, the UN atomic watchdog agency has said.

The International Atomic Energy Agency made the statement in a confidential report distributed to member countries that was seen by the Associated Press.
