Iran threatens to withdraw from the nuclear treaty if European sanctions are reimposed.

An Iranian official warned that Iran may withdraw from the nuclear non-proliferation treaty if European countries reimpose sanctions. This comes before a meeting with Britain, France, and Germany to discuss Iran's nuclear program and potential sanctions. The Europeans threaten to trigger a "snapback" that would reimpose sanctions if no progress is made on limiting Iran's nuclear activities by August. If Iran does withdraw, it would follow North Korea as the second country to do so. The US is also seeking to negotiate a new deal with Iran on its nuclear program.
