Iran Faces Sanctions Showdown: Nuclear Talks with Europe Amid Threats to Exit Treaty

Iran is set to hold urgent nuclear talks with Britain, France, and Germany (the E3) in Istanbul as European powers threaten to reimpose UN sanctions over Iran's nuclear program.

Tehran has warned it may withdraw from the Nuclear Non-Proliferation Treaty if sanctions are reinstated, escalating tensions. Iran is also seeking support from Russia and China to counter Western pressure and avoid the 'snapback' of sanctions. The talks come as the deadline for a new agreement approaches, with both sides blaming each other for the collapse of the 2015 nuclear deal.

The outcome could have major implications for regional security and global non-proliferation efforts.
