Iran talks aim for understanding this week, not end game: European official

Talks between major powers and Iran on Tehran's nuclear program aim to reach an understanding on key issues this week, but this week will not be the "end game" in the long-running negotiations, a senior European official said on Wednesday. "What we'd like to achieve by the end of this week is an understanding on the key issues, key parameters," the official said, speaking on condition of anonymity.
