Iran negotiator says hopes for deal, can't promise one by Tuesday
"I cannot promise whether the remaining issues can be resolved tonight or tomorrow night. Some issues still remain unresolved and until they are solved, we cannot say an agreement has been reached," Iran's Tasnim news agency quoted Deputy Foreign Minister Abbas Araqchi as saying in Vienna.
Iran's state news agency IRNA reported that Araqchi added, "There is hope."
