The IAEA Board of Governors, made up of representatives from 35 countries, adopted a resolution on Thursday requiring Iran to enhance its cooperation with the UN nuclear agency and submit a "comprehensive" report on the development of Tehran's nuclear program by spring.
Western powers that proposed the resolution aim to pressure Iran into entering negotiations for new restrictions on the advancement of Tehran's nuclear program.
There are doubts about whether the elected U.S. President Donald Trump will support negotiations once he takes office in January, Reuters reports.
Iran frequently expresses outrage over resolutions directed against its leadership, which is developing nuclear technologies despite resistance from major world nuclear powers.
