The US says it has taken control of four Iranian fuel shipments bound for Venezuela in the largest-ever seizure of its kind.

About 1.1 million barrels of fuel were confiscated "with the assistance of foreign partners", according to the Justice Department.
Washington said the shipments violated US sanctions.
Iran's ambassador to Venezuela claimed that neither the ships nor their owners were Iranian.
A judge issued a warrant for the seizure of the oil cargo from the four tankers after the US filed a lawsuit last month.In a statement on Friday, the US Justice Department said it had "successfully executed the seizure" of "a multimillion dollar fuel shipment by the Islamic Revolutionary Guard Corps (IRGC)."
The IRGC is a branch of the Iranian armed forces that the US has designated a foreign terrorist organisation.
"This seized property is now in US custody," the statement said, without specifying when or where the seizures took place.
