President Trump said “very good conversations” are taking place with Iran after warning the U.S. may start “dropping bombs again” if no deal is met by next week when the ceasefire with Iran expires. It comes as Iran is declaring the Strait of Hormuz closed in response to the U.

Iran warned mariners that the strait was again closed. Shipping sources said at least two vessels reported coming under fire.

President Trump is portraying peace talks with Iran as nearly complete and predicting a quick wrap-up of the war, but Iran is pushing back on several fronts, including the president's claim there's a deal over Iran's stockpile of Uranium.

It would also require a political understanding on just where Iran’s enriched uranium could be sent. “It probably would be the most complex uranium removal operation in history,” said Andrew Weber, a senior fellow at the Council on Strategic Risks and a former Pentagon official who was involved in past removal operations.

President Trump said U.S. negotiators will head to Pakistan on Monday for another round of talks with Iran, raising hopes of extending a fragile ceasefire even as Washington and Tehran remain in a standoff over the Strait of Hormuz.
