European Union foreign policy chief Catherine Ashton said she was "still waiting" for Iran to propose ways to prove to the International Atomic Energy Agency and the world that it is not seeking nuclear weapons.
In talks with Iran in Istanbul, Turkey, earlier this year, six global powers offered "a series of ideas for ways in which Iran could move forward with all of us and demonstrate to the IAEA that it was serious about turning away from the path of nuclear weapons and was seeking a civil nuclear programme," Ashton said in remarks made at a press conference in Moscow on Thursday after talks with Russian Foreign Minister Sergei Lavrov.

She said she had told the Iranian negotiator Jalili at the time at the end of the conversation "that we left those ideas on the table and we were open for their ideas to put on the table. And I'm still waiting for a response."
"I believe that dialogue is the best way to achieve the outcome that we all want for the safety and security of the people of Iran and for the region and beyond," Ashton added.
She continued, "The Iranians have obligations that they have signed up to and they must make sure that they meet those obligations. And that is why it falls to the international community to put the pressure on to make sure those obligations are met."
Russia earlier this week criticized the IAEA nuclear watchdog report that Iran appeared to have worked on designing an atom bomb, saying it contained "no new evidence."
Moscow vowed its opposition to any new sanctions against Tehran in the UN Security Council and urged a revival of talks between Tehran and global powers.
