WASHINGTON -- The United States says it has not received definitive confirmation from Iran of a date and venue for talks about Tehran's disputed nuclear program.
U.S. State Department spokesperson Victoria Nuland said: "It has simply been interesting to us that we are getting different signals out of Iran as to whether all of [the details are] locked down."
On March 31, U.S. Secretary of State Hillary Clinton said talks between Iran and the P5+1 -- the five permanent members of the United Nations Security Council plus Germany -- would take place in Istanbul on April 13-14.
On April 2, Russia said details of the meeting -- aimed at salvaging a diplomatic solution to the dispute over Tehran's nuclear program -- have not been definitively set, and that it could occur later than April 14.
