TEHRAN, April 9 (Xinhua) — Iran on Thursday announced two alternative routes for vessels transiting the Strait of Hormuz, citing risks from sea mines in parts of the vital waterway.“All vessels intending to transit the Strait of Hormuz are advised to take alternative routes to ensure maritime safety and avoid potential sea mine hazards,” Iran’s Islamic Revolutionary Guard Corps said in a statement carried by local media.The move comes as Iran has agreed to temporarily reopen the strait — a key oil shipping lane that typically handles one-fifth of global crude — as part of a two-week truce.
