The U.N.'s International Atomic Energy Agency declared that Iran is non-compliant with its nuclear obligations in a key vote. It is the first time Iran has been non-compliant in 20 years. The move could lead to further tensions and set in motion an effort to restore United Nations sanctions on Tehran later this year.

The UN atomic watchdog’s board has for the first time in two decades declared that Iran is in breach of its non-proliferation obligations as the US and European powers increase pressure on Tehran over its nuclear activities.
