Iran said on Monday its parliament was preparing a bill that could push the Islamic Republic towards exiting the nuclear Non-Proliferation Treaty.

The International Atomic Energy Agency declared Iran was in breach of its Nuclear Non-Proliferation Treaty obligations by failing cooperate with an probe into undeclared nuclear material and activities at multiple sites.

The United Nations atomic watchdog said there’s no indication of increased radiation levels at Iran’s main uranium-enrichment site, an early sign that Israel’s strikes haven’t penetrated the containment layers protecting the Islamic Republic’s nuclear stockpile.
