Iran on Friday announced that the Strait of Hormuz would be open to commercial ships. However, ships must follow rules set by Iranian maritime authorities, Iran's Foreign Minister Abbas Araghchi said. It was not clear in the announcement whether Tehran would be charged a fee for this. Tehran has been collecting tolls from ships passing through Hormuz for some time. Tasnim News quoted a source close to Iran's Supreme National Security Council as saying that commercial ships would only be allowed to proceed in coordination with the Iranian military. According to the Tasnim report, ships with ties to enemy countries would not be allowed to enter or leave. Iran's announcement came shortly after a ceasefire between Lebanon and Israel came into effect. 'The Strait of Hormuz has been declared completely open to all commercial ships for the duration of the ceasefire,' Foreign Minister Abbas Araghchi wrote on social media. US President Donald Trump thanked Iran in a post on social media on Friday. However, he also warned that the blockade imposed by the US Navy on Iranian ports would remain in place until an agreement is reached. After Iran closed the Strait of Hormuz, the US responded by blocking tankers going to Iranian ports to pick up oil. Earlier, on April 7, Trump announced a ceasefire with Iran with an agreement to open the Strait of Hormuz. During that time, an agreement was made that no one would attack Iran or any of its allies. However, Israel continued to attack Lebanon, claiming that the agreement did not mention the fight against the Lebanese armed group Hezbollah. US President Trump also supported Israel's claim and said that the agreement did not include a ceasefire in Lebanon. Iran also took a stand that it would not open the Strait of Hormuz until the attacks on Lebanon stopped.
