Iran said it was tightening control over the Strait of Hormuz on Saturday, warning mariners that the energy lifeline was again closed, as shipping sources said at least two vessels reported coming under fire while trying to transit the waterway.
Tehran said it was responding to a continued U.S. blockade of Iranian ports, calling it a violation of their ceasefire, while Supreme Leader Mojtaba Khamenei said Iran's navy was ready to inflict "new bitter defeats" on its enemies.
