U.S. safety firm withdraws certification for two oil tankers over Iran sanctions
LONDON, Jan 21 (Reuters) - Two tankers have had their environmental and safety classification withdrawn by a U.S. company that provides such certification, after accusations by a U.S. advocacy group that they had shipped cargoes of Iranian oil, documents seen by Reuters show.
Countries targeted by tougher U.S. sanctions, including Iran and Venezuela, have responded to the mounting pressure with elaborate strategies to circumvent restrictions on their oil exports.
