Iran and other world powers are holding talks for a second day on Iran's nuclear program.
Officials said the first day of talks in Moscow on June 18 appeared to make little progress, with both sides apparently unwilling to compromise.
The talks between Iran and six other world powers -- the United States, Britain, France, Russia, China and Germany -- are taking place following unsuccessful rounds of talks between the parties in Istanbul and Baghdad in the past two months.
Iran says its nuclear program is peaceful, and wants world powers to recognize its right to enrich uranium -- a process that can be directed to make both reactor fuel and nuclear warheads.
Iran is also demanding that the European Union rescind an embargo on Iranian oil imports to the EU that is due to come into effect July 1.
