The United States and Iran continue to remain at odds amid peace negotiations, with several key points unresolved.
One of the main sticking points is Iran's nuclear programme and ambitions, with the US demanding that Tehran surrender its enriched uranium stockpile.
Another issue is the exclusion of Lebanon from the deal, with Israel maintaining its right to defend itself on all fronts, including Lebanon.
The US has also stated that it will only release Iranian assets after the Strait of Hormuz is reopened, which has been a major point of contention.
An Iranian delegation is currently in Qatar for further negotiations, but the deal remains uncertain.
