Iran's oil minister, Mohsen Paknejad, has resigned, and Hamid Bovard, head of the National Iranian Oil Company (NIOC), has been named acting minister.
Mehdi Tabatabaei, deputy head of communications at the president's office, said President Masoud Pezeshkian accepted the resignation on Sunday and that Paknejad had asked to leave for personal reasons some time ago.
The change comes as the United States maintains a naval blockade of Iranian ports. US Treasury Secretary Scott Bessent said on Saturday that Iran had no oil shipments remaining at sea and would generate no oil revenue this week. Iran's central bank governor said in August that the country's oil exports had fallen to zero.
