US warns shipping firms of sanctions over payments to Iran for Strait of Hormuz passage

The United States has issued a warning to shipping companies regarding potential sanctions for payments to Iran related to passage through the Strait of Hormuz, escalating tensions between the two countries. Iran has disrupted traffic in the strait following recent conflict and has been charging fees for limited passage. The US imposed a naval blockade on April 13, restricting Iranian oil tankers from leaving the region.
