Iran reimposed restrictions on the Strait of Hormuz on April 18, 2026, after briefly reopening it — explicitly tying the closure to the ongoing US naval blockade of Iranian ports. Iranian gunboats fired on a commercial tanker attempting transit, marking an escalation in the dueling blockade strategy both sides are pursuing. The Strait handles roughly one-third of global seaborne oil, so the closure will tighten energy markets and likely push crude prices higher. The post's hashtags (#WarCrimes #RegimeChange) frame this as criminal escalation, but the core facts—Iran's reversal and the blockade linkage—are well-documented by AP, Reuters, and major outlets.
