The captain of the Adrian Darya 1 isn't the only one getting a big cash offer from the US.

The US Department of State is offering up to $15m in rewards for information that disrupts the sale of Iranian oil that allegedly funds the Iranian Revolutionary Guard, a group the US considers a terrorist organization.

Anyone with information on guard finances, oil-for-money schemes, front companies, financial institutions doing business with the guard, donors or investments are eligible for the funds, which are paid out through the 35-year-old Rewards for Justice counterterrorism program.
