Event Summary

Iran seized an oil tanker in the Gulf of Oman, claiming it was carrying six million litres of contraband diesel fuel. The vessel had 18 crew members from India, Sri Lanka, and Bangladesh. This incident follows a previous seizure by Iran last month and occurred two days after the United States seized an oil tanker off Venezuela's coast, which Washington alleged was transporting oil from Venezuela and Iran.
