@foxnews: The U.S. military is still keeping a close watch on one of the world's most critical waterways as tensions continue to simmer across the Middle East. Fox News' Jennifer Griffin reports from Washington that Sunday was the first day since March 2nd that Israel and Hezbollah didn't fire at each other, while the Strait of Hormuz remains a major focus in U.S.-Iran negotiations. CENTCOM says 55 merchant ships carrying more than 17 million barrels of oil safely transited the waterway — a reminder of what's at stake if the region's tensions escalate further.
