Victims of the Sept. 11, 2001, attacks asked a US judge to order the seizure of Iranian crude oil from a tanker owned by an American private equity firm, to help satisfy a $3.61 billion judgment against Iran over the attacks.
The request came in filings on Thursday with the US District Court in Manhattan.
Dozens of attack victims and their families said the Suez Rajan, owned by Los Angeles-based Oaktree Capital Management and idling in Southeast Asia, appeared to be carrying up to 1 million barrels of Iranian oil, violating US sanctions.
They said the oil should be sold to help cover their February 2018 judgment against Iran over that country's providing material support to al-Qaeda related to the attacks. Iran has long denied such claims.
Oaktree has about $166 billion of assets under management. Neither the firm nor its London-based Fleetscape unit, which finances the Suez Rajan, immediately responded on Friday to requests for comment.
The request came after the nonprofit United Against Nuclear Iran, which uses satellite images to track tanker movement, wrote Oaktree on Feb. 15 that the Suez Rajan appeared to have taken on the oil from another tanker two days earlier.
Even if the oil were seized, sales proceeds at current prices would cover only about 3% of the $3.61 billion judgment.
Victims said about $3.44 billion is outstanding, with the National Iranian Oil Co and National Iranian Tanker Corp, both under US sanctions, among the entities responsible to pay it.
Judgments against accused state sponsors of terrorism are often impossible to enforce.
On Feb. 18, Fleetscape said the Suez Rajan was operated by Empire Navigation, and that it had no role operating Empire's fleet. It also said it took accusations of US sanctions violations seriously.
Empire, based in Athens, said on Feb. 21 it was also investigating the matter.
Nearly 3,000 people died on Sept. 11, 2001, when planes were flown into New York's World Trade Center, the Pentagon in northern Virginia, and a Pennsylvania field.
The cases are Hoglan et al v Oaktree Capital Management LP et al, US District Court, Southern District of New York, No. 11-07550; and In re Terrorist Attacks on September 11, 2001 in the same court, No. 03-md-01570.
