On April 13, 2025, the Khatam al-Anbiya Construction Headquarters in Iran declared the U.S. maritime blockade of Iranian ports as "piracy" and warned that no port in the Persian Gulf or Sea of Oman would be safe if the blockade is implemented. The same day, U.S. President Donald Trump announced that the U.S. Navy would commence the blockade of Iranian ports and the Strait of Hormuz starting at 5:30 p.m. Tehran time on Monday.
