Iran's semiofficial news agencies have published a chart suggesting the Revolutionary Guard placed sea mines in the Strait of Hormuz during the war. The reports from the ISNA news agency and Tasnim, which is believed to be close to the Guard, show a "danger zone" over the Traffic Separation Scheme. That route is used by ships through the strait. It suggests ships travel north through waters closer to Iran’s mainland. The dates on the chart ran from February 28 to Thursday, April 9. It’s unclear if the Guard cleared the mines. This likely serves as a pressure tactic in two-week ceasefire and ahead of possible negotiations in Islamabad.
