U.S. President Donald Trump accused Iran of violating the cease-fire saying it was reneging on its promise to allow tankers through the Hormuz Strait.

Iran is reportedly planning to demand that shipping firms pay tolls in cryptocurrency to let their oil tankers through the Strait of Hormuz.

Trump said the temporary ceasefire is "subject to the Islamic Republic of Iran agreeing to the COMPLETE, IMMEDIATE, and SAFE OPENING of the Strait of Hormuz."
