The United States has warned Greece and other ports on the Mediterranean not to assist the Iranian oil tanker Adrian Darya 1, which transports around 2.1 million barrels of oil and $995,000, to avoid the violence and death that would be instigated with the money obtained from the sale of that cargo.

The Justice Department issued a warrant for the seizure of the ship on Aug. 16 in order to confiscate the oil and money, accusing it of violating sanctions against Iran. The assets would assist Iran’s Revolutionary Guard, which is designated as a terrorist by Washington.

“We have conveyed our strong position to the Greek government on the matter, as well as all ports in the Mediterranean that should be forewarned about facilitating this vessel,” the State Department said on the matter, according to The Wall Street Journal.

In addition, U.S. Secretary of State Mike Pompeo said the sale of oil transported by the Adrian Darya 1 would benefit Iran’s Quds Force.

“If they are successful they will have more money, more wealth, more resources to continue their terror campaign, to continue their assassination campaign. This is what we’re trying to stop,” said Pompeo, according to VOA.

The Quds Force is a unit of Iran’s Revolutionary Guard aimed at carrying out war activities and considered one of the most powerful security agencies in the Middle East.

The Iranian government is also accused of supporting various conflicts in the region.

President Donald Trump stated on July 22 at the White House that Iran is the “number one terrorist state in the world.”

Tensions between Washington and Tehran have escalated over Iran’s nuclear activities.

Iran announced July 7 that it is pursuing uranium enrichment, which would eventually allow it to manufacture nuclear weapons, posing a danger to the world, according to Pompeo.
