A senior Iranian diplomat said reaching a final nuclear deal with the world powers by the November 24 deadline is difficult, FARS news agency reported.
"Since all issues are interwoven, this makes the job difficult and obtaining results by November 24 is really a tough job; our time is really limited, yet we are not disappointed," senior Iranian negotiator and Deputy Foreign Minister Seyed Abbas Araqchi told reporters in Masqat.
Oman hosts a meeting for representatives of Iran and the Group 5+1 (the US, Russia, China, Britain and France plus Germany).
Araqchi, who was speaking after two days of talks among the top diplomats of Iran, the US and the EU, underlined that negotiations are intensely underway on the volume of Iran's nuclear reserves, installations, the heavy water reactor in Arak and the enrichment facilities in Fordo.
