U.S. Central Command said it will launch a blockade of Iranian ports beginning Monday at 10 a.m. ET.

In a statement, CENTCOM said the measure would be applied impartially against "vessels of all nations” that enter or leave Iranian ports and coastal waters. 

Ships traveling between non-Iranian ports will still be permitted to pass through the Strait of Hormuz, it added.

The command said the blockade will cover all Iranian ports and noted that additional guidance will be provided to commercial vessels ahead of its implementation.
