World powers and Tehran are close to a deal on Iran's nuclear talks and the marathon negotiations look set to be successfully concluded "in the coming days," Russia's top negotiator said Thursday.
   
"I can't predict how many hours it will take to resolve this situation. But all parties are of the opinion that this matter will be resolved in the coming days," negotiator Sergei Ryabkov told the Russian TASS news agency.
   
He added that the text Iran and the P5+1 world powers were working on to outline the deal was "91 percent finished".
   
Russia's deputy foreign minister also praised Thursday's visit to Tehran by the head of the International Atomic Energy Agency (IAEA), Yukiya Amano, which Ryabkov said helped to bring "greater clarity" to the negotiations.
   
Iran and the P5+1 group -- the United States, China, Russia, Britain, France and Germany -- have effectively given themselves until Tuesday to reach a deal.
