⚡ Key Points

The US Central Command announced that a blockade operation targeting all state vessels entering and exiting Iranian ports and coastal areas will commence at 10 PM Taiwan time on the 13th.
This blockade will cover Iranian ports within the Arabian Gulf and Gulf of Oman, while not impeding freedom of navigation for vessels heading to non-Iranian ports.
This action follows the collapse of ceasefire negotiations and appears to be an adjustment from former President Trump's previous threat to blockade "any and all vessels."

The US Central Command today issued a press release stating: "This blockade operation will be executed uniformly against all national vessels entering and exiting Iranian ports and coastal areas, including all Iranian ports located in the Arabian Gulf and Gulf of Oman."

The United States has renamed the Persian Gulf as the Arabian Gulf.

The press release also stated: "Central Command forces will not impede the freedom of navigation for vessels traveling to non-Iranian ports through the Strait of Hormuz." This appears to be an adjustment from Trump's previous announcement on social media to blockade "any and all vessels." (Compiled by Ho Hung-ju) 1150413
