US asks Iran to publicly state Hormuz is open
Washington is now demanding that Tehran issue a public statement declaring that the Strait of Hormuz is open and that vessels transiting the strategic waterway will no longer be attacked, senior US officials told AP. They added that the Islamic Republic's internal power struggles have made it difficult to reach and maintain a deal.
The officials also said the resumption of strikes earlier this week came after what they described as an attempt by a rogue faction of Iranian hard-liners to sabotage the ceasefire between Tehran and Washington.
The remarks came days after the US and Iran traded strikes over two days following Tehran's attacks on several ships transiting the Strait of Hormuz. Trump said on Wednesday that the ceasefire was over. However, Washington is reportedly planning to continue technical talks aimed at ending the conflict in the Middle East.
