Iran has announced the temporary closure of the Strait of Hormuz for live fire military drills. The rare show of force came as its negotiators held another round of indirect talks with the United States over its disputed nuclear program. It was the first time Iran has announced the closure of the key international waterway since the U.S. began threatening Iran and rushing military assets to the region. Iran's foreign minister expressed optimism about Tuesday's talks. U.S. Vice President JD Vance was more circumspect, saying, “In some ways, it went well,” but noting it was clear that wide gaps remained. The two sides are expected to hold more negotiations in two weeks.
