Iran on Saturday said that it closed the Strait of Hormuz because of Israel’s attacks in Lebanon and warned that while negotiators were going to Switzerland for talks with the US on their interim agreement, not much likely will happen if the fighting does not stop.US President Donald Trump, in response, threatened to impose US tolls in the crucial waterway if a final deal with Iran is not reached in 60 days, saying the money would be for “services rendered as the Guardian Angel to the countries of the Middle East”.His social media post underscored that the agreement calls for toll-free travel for 60 days.The announcements indicated a rough start to technical-level US-Iran talks that key mediator Pakistan said will begin on Sunday, with Qatari mediators also taking part.Iran’s joint military command said the strait was closed because of the US “clear breach of its commitments” by failing to end the war. The interim deal is meant to stop fighting on all fronts.Journalists set up near an access to the Burgenstock luxury hotel complex above Lake Lucerne on Friday, where talks following up on a deal to end the Middle East conflict were scheduled to begin.
