International Atomic Energy Agency (IAEA) Director General Yukiya Amano waits a board of governors meeting to commence at the IAEA headquarters in Vienna November 20, 2014.

'I call upon Iran to increase its cooperation with the agency and to provide timely access to all relevant information, documentation, sites, material and personnel,' Yukiya Amano, director general of the International Atomic Energy Agency, told a meeting of the IAEA's 35-nation board of governors.

Iran and six world powers, also meeting in the Austrian capital this week, aim to reach a diplomatic agreement by a Nov. 24 deadline to end a 12-year dispute over the Islamic Republic's atomic activities.
