US President Donald Trump on Monday reimposed the US Navy blockade in the Strait of Hormuz amid the collapse of the ceasefire in the four-month-long war in the Gulf.

However, the biggest change made to the blockade includes the 20 per cent fee on all Hormuz transits, which he said would be levied "as a matter of fairness".

This new shipping fee, expected to impact the global supply chain crisis caused by the war, will be reimbursed at the rate of 20 per cent on all cargo shipped, "for any and all costs necessary to do the job of providing safety and security to this very volatile section of the World", he wrote in a Truth Social post on Monday.

He added that the "process and formation" of what he called the "Iranian blockade" would begin immediately, clarifying that the blockade would stop Iran-linked ships and Tehran's customers from entering or exiting the strait.

He promised that all other countries would have fair and open use of the Strait of Hormuz, now managed by the US, which he called the 'Guardian of the Hormuz Strait'.

Like at various points during the war, Iran's Islamic Revolutionary Guard Corps (IRGC) had earlier declared that it would not allow Washington to intervene in the management of the crucial waterway, where cargo flows have again fallen steeply due to security concerns.

The new transit fee marks a major turning point in the war in the Gulf, a month after Trump himself had pushed back against Iran over Tehran levying tolls for safe passage in the strait.

During negotiations in June, he had also claimed on Truth Social that Iranian negotiators told him that there would be "NO TOLLS, NO INSURANCE COSTS, & NO OTHER CHARGES OF ANY KIND BEING SOUGHT OR RECEIVED BY IRAN ON SHIPS”.

At least one person was killed and seven others were injured in a US strike on a military base in Nain in Iran's Isfahan province.

The latest wave of strikes by the "terrorist American army" has so far killed two Iranians, reports from Al Jazeera and local Iranian media said.

A Tasnim report stated that Iran, on its part, has also been retaliating strongly, shooting down the US-made ‘Lucas’ suicide drone over Bandar Abbas on Monday, and launching its fifth wave of aerial strikes on US-linked military facilities in Bahrain and radar facilities in Oman.
