CAIRO/DUBAI, July 15 (Reuters) - The U.S. said it had begun a new wave of strikes against Iran on Wednesday after reimposing a naval blockade of Iranian ports, while Iran threatened to shut off more regional energy exports.
The strikes mark the latest escalation of attacks and counterattacks launched by the two sides as they vie for control of the Strait of Hormuz, which carried about a fifth of global oil and gas shipments before the war.
