A ceasefire deal to pause the war in Iran appears to be hanging by a thread after the Islamic Republic closed the Strait of Hormuz again in response to Israeli attacks in Lebanon. The White House demanded Wednesday that the channel be reopened and sought to keep peace talks on track. The U.S. and Iran both claimed victory after reaching the agreement, and world leaders expressed relief, even as more drones and missiles hit Iran and Gulf Arab countries. Israel intensified its attacks on the Hezbollah militant group in Lebanon, killing at least 182 people in one of the deadliest days in the latest Israel-Hezbollah war.
