[Photo/Agencies] TEHERAN/BRUSSELS - Iran said on Monday it may extend an agreement allowing UN inspectors to monitor some key activities if talks with world powers on its nuclear program continue "on the right track". Talks have been held in Vienna aimed at getting the United States to return to a 2015 deal abandoned by then-US president Donald Trump and lift sanctions, and to bring Iran back to full compliance with nuclear obligations it retreated from in response.
