Iran Will Seek Nuclear Weapons if US Attacks, Top Official Says: 'No Choice'

Iran "will have no choice" but to seek nuclear weapons if attacked, an adviser to Supreme Leader Ayatollah Ali Khamenei has warned.

The statement comes in response to U.S. President Donald Trump's threat to bomb Iran if it does not agree to a new nuclear deal.

Newsweek has reached out to the State Department and Iran's foreign ministry for comment.
