Former U.S. President Donald Trump vowed that the United States would sink any Iranian ships that attempt to challenge a blockade. The military had scheduled the blockade to begin, but no official announcement or interception of vessels was reported as the deadline passed.

The U.S. military said the blockade would begin at 1930 hours IST and apply to all ships leaving or seeking to dock at Iranian harbours, but as the deadline passed there was no announcement that the measure had come into effect, nor sign of any interceptions
