Iran has announced the closure of the Strait of Hormuz, a vital global shipping lane, in response to reported US military actions against Iranian targets overnight. The closure is indefinite, according to Iranian authorities, who cite the strikes as justification. Vessels that previously received permission to transit the strait have been asked to exercise patience and await further instructions. The Strait of Hormuz is strategically crucial for oil and gas transport, connecting the Persian Gulf to the Arabian Sea and beyond. This closure raises concerns about potential disruptions to global energy supplies and maritime trade. The move follows reported US strikes within Iran, details of which are still emerging. Further developments are expected as international reactions unfold.
