Iran has sold the oil from a tanker released by Gibraltar after weeks in the custody of British Royal Marines and the vessel’s owner will decide on its next destination, IRIB news agency quoted an Iranian government spokesman as saying on Monday. Separately, Tehran – embroiled in a spiralling confrontation with Washington over U.S. sanctions meant to strangle Iranian oil exports – announced that it had deployed a naval destroyer with cruise missiles to help secure Iranian ships. The Iranian government spokesman did not identify the recipient of the oil carried by the Adrian Darya tanker.
