US and Iran hold separate meetings in Qatar and agree to continue discussions

U.S. and Iranian negotiators met separately in Qatar with mediators, making 'positive progress' and agreeing to continue discussions after Iran's late Ayatollah Ali Khamenei's funeral. Key issues include control of the Strait of Hormuz and Lebanon, with Iran insisting on regulating shipping routes and charging fees, while the U.S. and Gulf states oppose such charges.
