Secretary of State John Kerry said Sunday that the temporary nuclear deal with Iran isn't a tacit agreement allowing the country to enrich some uranium without pursuing a nuclear bomb.

Kerry was responding to comments from Iran's foreign minister and Iranian President Hassan Rouhani saying that the deal amounted to a recognition of Iran's right to enrich.
