Two senior U.S. officials told NBC News that military commanders are allowing some Iranian missiles and attack drones to slip through air defenses due to a shrinking supply of anti-missile weapons. This strategy aims to preserve the U.S. Pentagon's limited missile inventory for critical operations. The U.S. military also reported firing on another merchant vessel attempting to breach its blockade of Iranian ports. This action comes amid ongoing tensions in the region, where multiple countries are engaging in or responding to conflicts involving Iran.
