The ceasefire between the US and Iran is being tested as both sides wrestled for control over the Strait of Hormuz. Iran ALSO launched its first missile and drone attack on the United Arab Emirates since a ceasefire with the U.S. took effect on April 8, and it fired two drones at a ship in the Strait of Hormuz, UAE authorities said Monday. The fresh volleys of missiles and drones came after US President Donald Trump launched a new effort to get stranded tankers and other ships through the strait, the vital energy-trade chokepoint that has been virtually closed since the US and Israel began attacks on Iran in February, a war that has killed thousands of people across the region.
