Madrid: Spain’s top criminal court is mulling legal action against President Bashar Al Assad’s uncle for laundering hundreds of millions of euros taken from Syrian state coffers, legal documents showed Friday.

According to documents filed at Spain’s National Court, Rifaat Al Assad is accused of running “a criminal group” responsible for laundering “more than 600 million euros” - around $660 million.

Operational since the 1980s, the group - which included eight of his sons, two of his wives and several frontmen - worked to “conceal, transform and launder ... funds illegally plundered from the Syrian state treasury,” it said.

The 82-year-old is facing similar charges in Paris, where he will go on trial on December 9 for allegedly laundering money from Syrian state coffers and using the proceeds to build up a 90-million-euro property portfolio in France.

In the documents released on Friday, National Court judge Jose de la Mata claims that Rifaat Al Assad brought more than $300 million out of Syria and began acquiring property in Spain in 1986, mostly in the Costa del Sol.

He and his family have since built up a huge portfolio of 507 properties in Spain, valued at around 695 million euros, legal documents show.

All his properties were seized by the authorities in 2017.

The court now has 10 days to formally open legal proceedings or to drop the case against him.

‘Butcher of Hama’

A former Syrian vice president, Rifaat Al Assad is known as the “Butcher of Hama” for allegedly leading troops that crushed a 1982 uprising in the central city of Hama, leaving between 10,000-40,000 people dead.

He left for France in 1984 after mounting a failed coup against his older brother Hafez Al Assad, the late father of Syria’s current president.

When he takes the stand in Paris next month, Assad will face charges of laundering the proceeds of aggravated tax fraud, embezzling Syrian state funds, and failing to register French security and cleaning staff.

His French fortune reportedly includes two Paris townhouses, a stud farm and a chateau, as well as 79,000 square feet of office space in Lyon, most of it acquired through offshore companies.
