The Wall Street Journal reports that the Iranian authorities have presented the administration of US President Donald Trump with a tough set of demands for resuming ceasefire talks.

Citing a source, the newspaper says Tehran wants Washington to revise the rules governing passage through the Strait of Hormuz so that Iran could charge ships transit fees under a model similar to the Suez Canal. Iran is also demanding the full removal of sanctions, guarantees that hostilities will not resume, an end to Israeli strikes on the Lebanese Hezbollah, and the right to keep its nuclear program without restrictions.

An unnamed American source described those demands as unrealistic and absurd. In that source’s view, Tehran’s position could seriously complicate any path toward an agreement.

Earlier, Trump said the United States was in talks with Iran, but Tehran rejected that claim as groundless. The US president also asserted that the Iranian side had supposedly agreed to permanently give up nuclear weapons.
