US sanctions Greece-, Panama-based law firm over aid to Iranian shipping

The US Treasury Department imposed sanctions on Wednesday on Karnakis & Karnakis, a law firm based in Greece and Panama, saying it had
for years provided legal assistance to Iranian shipping networks.
The US Financial Crimes Enforcement Network also issued an administrative subpoena to advance an investigation into a Greek bank over potential ties to Iran, according to a Treasury statement, which did not name the bank.
FINCEN also issued requests for information to six other European banks that it did not name over relationships with Iranian financial institutions under US sanctions.
