“Iranian security officials said they had closed the Strait of Hormuz, citing what they said was the U.S. failure to stop the fighting in Lebanon as required under the agreement signed earlier this week by President Trump,” the Wall Street Journal reports.“The announcement by Iran’s joint military command came as clashes between Israel and Hezbollah flared again in Lebanon on Saturday, just hours after the two sides agreed to a renewed ceasefire. It undid for now the main achievement of the deal, which was to set the stage for reopening a waterway vital to world energy markets.”“Even before Iran’s announcement, however, the recovery of traffic through the strait had been halting. Iran had imposed new procedures, including a demand that ships register to cross two days in advance, and wary shipowners were monitoring the still uncertain environment in the waterway.”Bloomberg: Iran says Strait of Hormuz has been closed.
