Meanwhile, a U.S. Coast Guardsman wounded in the boat attacks Saturday evening died, the third American service member killed in the blasts. Four other Americans also were wounded.
Oil minister suspected al-Qaida to be responsible for the blast. Insurgents already have repeatedly attacked a northern pipeline which carries crude to Turkey.
He said: "Those who are carrying out these terror actions don't want ... prosperity for Iraq."
Asked whether the attackers arrived at the port by traveling from inside Iraq or from neighboring Iran or Kuwait, Navy Commander James Graybeal, a spokesman for the U.S. Navy 5th Fleet headquarters in Bahrain said: "That's what we?re trying to determine."
