NEW YORK: US prosecutors on Tuesday charged an alleged financier of Lebanon’s Hezbollah with evading US sanctions imposed on him by exporting hundreds of millions of dollars worth of diamonds and artwork.

The US Treasury Department also unveiled sanctions on what it said was a vast international money laundering and sanctions evasion network, targeting 52 people and entities over the payment and shipment of cash, diamonds, precious gems, art and luxury goods for the benefit of Nazem Ahmad.

The Treasury in 2019 sanctioned Ahmad for allegedly providing material support to Lebanon’s Hezbollah, which Washington considers a terrorist organisation. The move was intended to cut off access for Ahmad and 11 businesses associated with him to the US financial system.

But federal prosecutors in Brooklyn said Ahmad worked with three family members and five other associates to continue dealing in diamonds and artwork, while concealing Ahmad’s involvement. One of the alleged co-conspirators, Sundar Nagarajan, was arrested on Tuesday in England.

British police said Nagarajan’s arrest was related to suspected terrorist financing and money laundering, which is believed to be connected to Ahmad, adding that extradition proceedings had began.

Ahmad remains at large.

The investigation “speaks to the unwavering commitment of the US and UK governments to prevent art and diamond markets from becoming a haven of illicit financial activity,” said Tae Johnson, acting director of US Immigration and Customs Enforcement, whose investigative arm probes sanctions violations.

Prosecutors said Ahmad in 2021 directly negotiated the sale of artwork with a New York-based artist, whom he instructed not to mention his name. Six paintings by the artist valued at nearly $200,000 were then exported to a Lebanese company used by Ahmad, prosecutors said.

In total, entities tied to Ahmad engaged in more than $440 million in financial transactions in violation of sanctions, including importing $207 million worth of goods to the United States and exporting $234 million worth of mostly diamonds and artwork, prosecutors said.

The Treasury’s action imposed sanctions on dozens of people and entities in Lebanon, South Africa, Angola, Cote d’Ivoire, the Democratic Republic of the Congo, Belgium, the United Kingdom and Hong Kong, and warned that Ahmad directs a global network that takes advantage of the permissive nature of the global diamond, precious gems and art market.

Earlier on Tuesday, Britain also sanctioned Ahmad over suspicions he was financing Hezbollah, which is backed by Iran.

The British government said Ahmad has an extensive art collection in the UK and does business with several UK-based artists, galleries and auction houses.
