As the United States and Iran come closer to a historic nuclear deal, many U.S. states are likely to stick with their own sanctions on Iran that could complicate any warming of relations between the long-time foes.
U.S. Secretary of State John Kerry defended on Sunday his presentation of a framework agreement on Iran's nuclear program after a different interpretation was offered by Iran's supreme leader, and a prominent U.S. senator said Kerry was "delusional."
An outline nuclear accord reached this month between Iran and world powers respects Iran's red lines, though ambiguities over the lifting of sanctions must be resolved, a top Iranian military official was quoted as saying on Saturday.
Iran's leader on Thursday condemned the military intervention by its main regional rival Saudi Arabia in Yemen as genocide, sharply escalating Tehran's rhetoric against the two-week-old campaign of air strikes.
