France's national finance prosecutor called Monday for a four-year prison sentence and a 10 million euro fine for Rifaat al-Assad, uncle of the Syrian president, accused of money laundering related to his vast property empire in France.

The prosecutor also called for the confiscation of all his real estate -- already seized -- valued at 90 million euros ($99.5 million).

The trial of the younger brother of the late Syrian president Hafez al-Assad -- the current president's father -- concerns crimes allegedly committed between 1984 and 2016, including aggravated tax fraud and misappropriation of Syrian funds.

Rifaat Assad, who divides his time between France and Britain, denies the charges.

The 82-year-old, dubbed the "Butcher of Hama" for allegedly commanding troops who put down an uprising in central Syria in 1982, has been under investigation in France since 2014.

Formerly Syria's vice president, Assad left his home country in 1984 after mounting a failed coup against his brother Hafez, who led Syria from 1971 to 2000.

After he arrived in Europe, Rifaat al-Assad's lavish lifestyle, four wives and 16 children soon raised eyebrows.

His reported French fortune includes two Paris townhouses, one measuring 3,000 square metres (32,000 square feet), as well as a stud farm, a chateau and 7,300 square metres of office space in Lyon.

He and his family also built up a huge portfolio of 507 properties in Spain, valued at around 695 million euros, Spanish legal documents show. All his properties in that country were seized by the authorities in 2017.

Assad has maintained that his lifestyle was made possible by gifts from the Saudi royal family amounting to more than a million dollars per month.

But while Assad's lawyers claimed to document gifts of almost $25 million between 1984 and 2010, French investigators registered transfers from Saudi Arabia totalling only $10 million.

Assad's trial opened on December 9, and his defence will present its case on Tuesday.

This is only the second trial of a foreign dignitary in France on charges related to "ill-gotten gains".

In the first, Equatorial Guinea vice president Teodorin Obiang received a three-year suspended jail term in October 2017 after being convicted of using public money to fund a jet-set lifestyle in Paris.
