On March 25, according to the Financial Times, Iran has circulated a letter to member states of the International Maritime Organization (IMO) stating that 'non-hostile vessels' can pass through the Strait of Hormuz after 'coordination with Iranian authorities.' In the letter, distributed to IMO member states on Tuesday, Iran's Ministry of Foreign Affairs stated that Iran has 'taken necessary and proportionate measures to prevent aggressors and their supporters from using the Strait of Hormuz to advance hostile actions against Iran.' Currently, approximately 3,200 vessels are stranded in the Persian Gulf, and at least 22 vessels have been attacked by Iran since the outbreak of the conflict. The IMO held an emergency meeting of its member states last week, and the organization is in negotiations to establish a humanitarian corridor for vessels facing severe supply shortages to leave the Persian Gulf. Recent ship tracking data indicates that Iran is allowing a small number of vessels to pass through a route within its territorial waters. Analysts believe this route allows Iranian authorities to verify the identity of vessels before allowing them passage.
