The U.S. confiscated Iranian oil on a tanker at sea in recent days in a sanctions enforcement operation, three sources said, and days later Iran seized another oil-laden tanker in retaliation, according to a maritime security firm.
As oil markets remain jittery, the cargo seizure is the latest escalation between Washington and Tehran after years of sanctions pressure by the U.S. over Iran's nuclear program. Iran does not recognise the sanctions, and its oil exports have been rising.
