U.S. Central Command said Tuesday it destroyed five Iranian crude oil tankers as retaliation for Islamic Revolutionary Guard Corps ballistic missiles fired at an American warship twice in two days. It marks the latest round of military action in a conflict with Tehran that’s now more than six months old.

Four of the vessels, the M/T Kaviz, Charminar, Horizon 1 and Riesco, were hit in the Gulf of Oman. The fifth, the M/T Derya, was struck near Kharg Island, Iran’s main oil export terminal. Centcom said crews were warned to abandon ship first, the warship evaded the missiles and no Americans were harmed. It described the tankers as part of a shadow fleet funding the IRGC.

Iran answered with missiles aimed at a U.S. base in Jordan. Jordan said it intercepted 18 of 20, with two landing in unpopulated areas and no casualties. Separately, Houthi strikes injured 73 people in Saudi Arabia, reports BBC News.

Oil is the transmission channel, and it’s already moving. Brent traded near $97 Tuesday afternoon, CBS News reported, then pushed toward $100 in early Asian trading Wednesday. That’s a seven-week high, per The Guardian. Iran has also warned tanker crews near Kuwaiti and Bahraini ports to abandon their vessels, which is less a threat than a shipping-insurance earthquake.

The U.S. Navy is still enforcing a blockade of Iranian ports as Tehran keeps a tight grip on commercial transit through the Strait of Hormuz, the narrow passageway long vital to the shipment of Middle Eastern oil and other commodities. Access to the strait, and the global economic implications of its closure, remains a major obstacle to ending the war.

Canadian whisky is about to get scarce. The White House moved Tuesday to ban imports of most Canadian alcoholic beverages, some dairy products including whey, and motorcycles, effective 12:01 a.m. Sept. 29. Molasses and nonalcoholic beer are on the list too.

The proclamations were signed under Section 338 of the Tariff Act of 1930, a rarely used provision aimed at countries that discriminate against U.S. commerce. They landed hours after Canada's retaliatory tariffs on about $20 billion in American goods took effect, NBC News reports. President Trump also directed the General Services Administration to make Canadian products ineligible for large, long-term federal contracts until Canada grants “full and fair reciprocity.” An added 50% tariff hits Canadian cheese, steel, aluminum and bamboo furniture next Tuesday, and a threatened 50% tariff on Canadian autos, trucks and parts remains on the table for Jan. 1, 2027 absent a deal.

For your bar cart and your grocery bill, that means fewer Canadian spirits and dairy inputs on shelves, and higher prices in the affected categories. How much fewer is genuinely unsettled. Formal negotiations still haven’t resumed since they collapsed last month, though officials on both sides say they remain in contact. Three weeks of silence, and the next tariff deadline is Tuesday. If you’ve got a favorite Canadian bottle, now would be the time.

Global test scores just hit a 20-year low. The 2025 Programme for International Student Assessment, given every three years to 15-year-olds, this round to 760,000 students across 91 countries, showed reading and math down nearly 20 points from the previous cycle. That’s serious.

The numbers that got everyone’s attention involve screens. Students who rarely used AI scored roughly 30 points higher than regular users, according to OECD data, and heavy in-school social media users trailed by about 44 points in math. The U.S. landed 27th in math and 13th in reading and science. China, Singapore and Japan took the top spots, as they tend to.

One caveat worth holding onto: the OECD’s own language is correlational, not causal. Nobody has proven that chatbots are hollowing out teenage brains—only that the kids using them most are the kids scoring lowest, which could run either direction.
