The United States and Iran have ended face-to-face talks without an agreement, leaving a fragile two-week ceasefire in the war in the Middle East in doubt.

Officials in Washington said the negotiations collapsed over what they described as Iran’s refusal to commit to abandoning a path to a nuclear weapon, while Tehran blamed the US for the breakdown of the talks without specifying the sticking points.
