June 14 (Reuters) - Most Gulf stock markets rose on Sunday, supported by growing optimism about a possible peace deal between the United States and Iran.

The leaders of the United States and Pakistan indicated that a long-awaited framework agreement might be signed today aimed at ending the months-long conflict between the United States and Iran. Qatari negotiators traveled to Tehran to help finalize the agreement.

But Iran questioned the timing of the agreement, saying that it had not made any final decision and that political, legal and technical reviews were still ongoing.
