Most Gulf stock markets ended higher on Wednesday, with Dubai leading regional gains, as optimism over a possible ceasefire grew following reports that Washington had submitted a 15-point proposal to Tehran aimed at ending the war.

Tehran denied that any direct talks had taken place, and the official IRNA news agency quoted an armed forces spokesperson on Wednesday as saying the U.S. was "negotiating with itself". Israel and Iran exchanged airstrikes on Wednesday.
