The Washington Post reports that empty tankers have begun entering Iranian ports in the Persian Gulf and loading oil, based on satellite imagery and ship-tracking data analyzed amid the ongoing U.S. blockade of Iran. This is consistent with reporting from NYT, NBC, PBS, and Bloomberg indicating Iran is attempting to move oil despite U.S. naval enforcement of the blockade since late February 2026. The Post's use of satellite imagery provides institutional-grade evidence, though the report doesn't quantify how much blockade capacity the tankers represent or whether Iran is successfully circumventing U.S. interdiction efforts versus simply attempting to do so.
