Iran announced the closure of the Strait of Hormuz on Saturday, a critical waterway for global oil transport. The decision, reported by Iranian state media, follows overnight Israeli strikes in southern Lebanon. Iran alleges these strikes constitute ceasefire violations, prompting the closure as a retaliatory measure. This action significantly raises tensions in the region, potentially disrupting international shipping and energy markets. The closure impacts a major chokepoint for approximately 20% of the world’s oil supply. No specific timeframe for reopening the Strait was provided. International reactions are anticipated as the situation develops, with concerns mounting over potential further escalation.
