The US-Iran confrontation lurched back toward open war this morning. CENTCOM said it struck Iranian radar and drone command-and-control sites at Goruk and on Qeshm Island over the weekend, eliminating air defenses, a ground control station and two one-way attack drones, after Tehran downed a US MQ-1 Predator over international waters; the IRGC answered with a missile strike on an air base it says was used in an American hit on a communications tower on Sirik Island, while Kuwait again intercepted incoming missiles and drones. Crude jumped on the exchange, with WTI up 3.6 percent to $90.48 and Brent up 3 percent to $93.87 as traders re-priced risk to Hormuz transit, and the rouble slipped about 1.1 percent to 71.84 against the dollar. USS Abraham Lincoln and USS George H.W. Bush remain on station together in the Arabian Sea; SENTINEL is tracking a heavy MENA-to-Europe airlift leg of fifteen movements (eight C-17As) and a nine-hull Atlantic tanker line, with Nimitz in the Caribbean, George Washington in the Philippine Sea, and tropical cyclone Jangmi (06W) churning the Western Pacific.

Ukraine pushed its long-range war on Russian energy logistics deeper still, with attack drones setting the Lazarevo pumping station in Kirov region ablaze, a node moving Siberian crude toward Black and Baltic Sea export terminals, roughly 1,300 km from the front, part of a widening campaign that also struck an Iskander system in Rostov Oblast late on May 29. Russia struck back at Odesa, where drones hit a residential district, part of attacks across Ukraine that killed three and wounded more than sixty. The political fallout from last week's Geran-2 impact in Galati hardened, with Bucharest expelling Moscow's Constanta consul and Foreign Minister Oana Toiu saying the strike could justify NATO Article 4 consultations. Japan, for the first time, finalized the deployment of four Self-Defense Forces officers to NATO's NSATU command in Wiesbaden.

In Lebanon, Israel seized the Crusader-era Beaufort Castle in its deepest incursion in more than a quarter of a century, pushing troops onto the Beaufort Ridge and into the Wadi al-Saluki valley above the Litani; a Hezbollah drone killed one IDF soldier and wounded three near the captured ridge, Israeli airstrikes killed six across the south, and Israel threatened to strike Hezbollah's stronghold in Beirut. An Israeli strike on a Gaza seaport cafe killed at least two Palestinians, and two more died in the occupied West Bank.

The daily brief synthesises SENTINEL's pattern detections (strategic airlift, tanker activity, infrastructure thermal anomalies, hazards), curated wire headlines, and the day's top-scored OSINT signals. It is regenerated each morning and fact-checked in a second pass before publication.
