Questions about when ships can safely move and which routes are viable remain unresolved. Bimco, the international shipping trade association, warns that public statements issued by both governments fall short of what the industry needs. "Due to lack of details and a history of overly optimistic reassurances, we believe the security situation for the shipping industry remains volatile, and we still consider it very risky for ships to commence transits at this point," said Jakob Larsen, Bimco's chief safety and security officer. Among the hazards Larsen flagged, mines loomed largest — a threat given additional weight by congressional testimony from Secretary of State Marco Rubio earlier this month in which he said Iran had seeded much of the strait with them.
