"The shipping sector is on notice that we will aggressivelyenforce U.S. sanctions," the official told Reuters days afterwarning countries not to allow the tanker to dock. Ship tracking data have shown the ship, theAdrian Darya,formerly calledGrace 1, last heading toward Greece, althoughGreece's prime minister said it was not heading to his country. The official, speaking on condition of anonymity, warnedthat the United States would act against anyone who directly orindirectly helped the tanker. "All parties in the shipping sector should conductappropriate due diligence to ensure that they are not doingbusiness with nor facilitating business for, directly orindirectly, sanctioned parties or with sanctioned cargo," theofficial warned. The ship was released from detention off Gibraltar after afive-week standoff over whether it was carrying Iranian oil toSyria in violation of European Union sanctions.
