Iran warned on Monday (May 4, 2026) that it would consider any U.S. attempt to interfere in the Strait of Hormuz a breach of the West Asia ceasefire, as U.S. President Donald Trump said the United States would begin escorting ships through the blocked waterway.

Negotiations between the two countries have been deadlocked since a ceasefire came into effect on April 8, and Iran's stranglehold on the strategic strait following U.S.-Israeli attacks on Tehran has been a main point of contention.
