The reopening of the Strait of Hormuz is at the heart of the Memorandum of Understanding (MOU) signed by the United States and Iran. Under the terms of the deal, the US will immediately lift its blockade of Iranian ports. The Islamic Republic, for its part, will reopen the Strait of Hormuz, and charge no toll for commercial vessels for a period of 60 days. However, the presence of sea mines in the vital waterway could be a cause for concern. Our correspondent Reza Sayah reports from the Strait of Hormuz.
