US Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi are heading to Switzerland for crucial talks.
The negotiations are centered on a 14-point memorandum of understanding aiming for a permanent ceasefire and regional stability.
A ceasefire between Israel and Hezbollah, mediated by the US and Qatar, is seen as a key factor for the talks.
The agreement includes provisions for easing sanctions, releasing frozen Iranian assets, and facilitating oil exports within 60 days.
