Iran’s Supreme Leader Ayatollah Seyyed Mojtaba Hosseini Khamenei said in a message Thursday that the management of the Strait of Hormuz will “certainly enter a new phase,” while vowing that Tehran will demand compensation for all war-related damages, Anadolu Ajansi (AA) reported.

The message, released by his office on the 40th day since the killing of his father, former supreme leader Ayatollah Ali Khamenei, described his death as a “heavy and historic blow” for the Iranian nation, and one of the most painful moments in its recent history.
