Iran said it attacked 10 ships near the Strait of Hormuz, including two U.S. vessels and eight oil tankers, after the United States said it had destroyed or sunk five Iranian oil tankers overnight. The exchange was described as the largest declared wave of reciprocal attacks on shipping since the six-month-old war began, pushing Brent crude above $100 a barrel for the first time since July. The Islamic Revolutionary Guard Corps said it also fired ballistic missiles at a base used by U.S. forces near Al Azraq in eastern Jordan. Jordan said its air defenses intercepted 18 of 20 missiles, with the other two landing in unpopulated areas and causing no casualties. A U.S. official said the strike was ineffective and all American personnel were accounted for. Shipping incidents included the death of one crew member and the disappearance of another aboard the Hercules Star off Dubai, while the New Andros, carrying 2 million barrels of fuel oil, caught fire after a reported drone strike in Iraqi waters. Iran threatened to escalate retaliation for further attacks. President Donald Trump predicted the war would end immediately after the U.S. midterm elections on Nov. 3, saying Tehran could not withstand further U.S. economic pressure, though he acknowledged negotiations remained possible.
