Iranian Foreign Minister Hossein Amirabdollahian said on Saturday that if Western nations show actual will, Iran is ready to “quickly finish” a deal in discussions to resuscitate its 2015 nuclear agreement with them.

“I’m taking a close look at the draft of the agreement… Western parties are aware of our red lines. “I’m ready to close a decent transaction right away if they show actual intent,” Amirabdollahian wrote on Twitter.

On Friday, a senior US State Department source said that while negotiators had made great progress in the last week or two in resurrecting the deal, there were still a number of difficult problems to resolve.
