US: There was 'modest progress' in Iran talks

The United States said on Tuesday it had seen possible progress in talks with Iran, but joined European negotiators in pressing for urgency in rolling back Tehran's nuclear program, AFP reports.

"There may have been some modest progress," State Department spokesman Ned Price told reporters in Washington, adding, "But it is in some ways too soon to say how substantive that progress may have been. At a minimum any progress, we believe, is falling short of Iran's accelerating nuclear steps and is far too slow."
