Iran-US Nuclear Talks on Brink of Collapse Over Venue Dispute; Trump Warns of 'Other Options'

• Planned US-Iran nuclear talks face collapse after Washington rejected Tehran's last-minute demands to change the negotiation venue and structure.
• Iran requested moving the talks from Istanbul to Oman and limiting them to bilateral nuclear issues, excluding missile programs and regional activities.
• US officials rejected Iran's demands, stating, "it is this or nothing," leading to uncertainty over the diplomatic process.
• Failure to hold talks could push President Donald Trump towards considering military action, a threat he has repeatedly made.
• The original plan involved parallel tracks: direct US-Iran nuclear discussions and multilateral talks with regional countries on broader issues.
