Iran and six powers are still apart on all main elements of a nuclear deal with less than two weeks to go to their June 30 target date, two diplomats tell The Associated Press.

They expect talks to be extended into July as a result.

Ways of implementing the deal are to be contained in four or five annexes to the main text of an agreement. But the diplomats on said that all of the annexes remain incomplete because of arguments over details.

The diplomats say the main document has dozens of blank spaces reflecting disagreement on up to 10 elements crucial to any deal.

They demanded anonymity because they are not authorized to comment on the confidential talks. They spoke ahead of a new round of negotiations Wednesday.
