A date for a fourth round of Iran-U.S. talks on Iraq's security will be set before mid-March, Iraq's foreign minister said Thursday, two weeks after Tehran postponed a previously scheduled expert-level meeting with U.S. diplomats. Iraqi Foreign Minister Hoshyar Zebari told the U.S.-funded Al-Hurra TV there had been "technical difficulties" in getting the two sides together. But a date for the next session will be confirmed before March 15, he said without elaborating. U.S. Embassy spokesman Philip Reeker said any announcement on dates for the next meeting should come from the Iraqis. After being informed of Zebari's remarks, Reeker said, "that sounds perfectly plausible to me. What I don't have is any date to announce."
