Nuclear talks with Iran were proceeding "positively", said a spokesman Saturday for European Union foreign policy chief Catherine Ashton, who is heading the Western delegation in Istanbul, DPA reported.
Michael Mann said the first two-and-a-half-hour session had been conducted in a "constructive" and "positive" manner.
The talks would reconvene with bilateral meetings after a 90-minute lunchbreak, he said. Mann, who earlier told dpa that no major breakthrough was expected in Istanbul, declined to give details of the bilaterals.
