Iran said on Sunday it has informed Ankara that Tehran is ready to hold talks in Turkey with the six world powers over its controversial nuclear programme, turning to a country seen as an ally. European Union foreign affairs chief Catherine Ashton, spearheading the negotiations with Iran for the world powers, last month proposed to hold the talks in Vienna where the UN nuclear watchdog is based starting November 15. "In the last two or three days, we informed our Turkish friends that we agree to hold negotiations in Turkey," Iran's Foreign Minister Manouchehr Mottaki told reporters, asked for a venue.
