VIENNA (AP) — Iran and six powers made some progress on drafting the wording of a nuclear deal Friday, but key sections of the document were left blank, reflecting significant differences on how much Iran needs to limit its nuclear program in exchange for full relief from sanctions.

Iranian Foreign Minister Mohammad Javad Zarif said full agreement was possible at the next round, in Vienna on July 2. At the same time he said there was no common text. Pressed for details after the meeting he said the two sides “agreed about the title” and about the “general framework” of what a final deal would look like.
