Sawt Falasteen - Ten on trial in Paris over 2016 gunpoint robbery of Kim Kardashian

Kardashian, 44, was traumatised and left Paris hours after the robbery on the night of October 2-3, 2016. She was not in court for the start of the trial but is due to testify on May 13 in a highly anticipated appearance.

Those on trial are mainly men in their 60s and 70s with previous criminal records and underworld nicknames like "Old Omar" and "Blue Eyes" that recall the old-school French gangsters of 1960s and 1970s films noirs.

The nine men and one woman on trial, while charged in connection with the robbery, are not currently in custody.

Kardashian, then 35, was threatened with a gun to the head and tied up with her mouth taped up. The theft was the biggest against a private individual in France in the past 20 years.

The trial will also go into how the perpetrators received the information as to where Kardashian was staying during Paris Fashion Week, and picked the very moment when her bodyguard was absent, accompanying her sister Kourtney to a night club.

It is thought Kardashian's frequent posts about her wealth, personal life and whereabouts may have facilitated the perpetrators' actions.

- Haul never recovered -

The star was staying at an exclusive hotel in central Paris favoured by celebrities when two armed and masked men stormed into her room at around 3:00 am after arriving at the establishment by bicycle.

They shouted that they wanted the diamond engagement ring from her now ex-husband, the US rapper Kayne West.

Kardashian had been showing it off on her social media channels -- it alone was valued at $4 million (3.5 million euros).

They made off with the ring among $10 million worth of jewels.

The only item recovered was a diamond necklace dropped in the street while the thieves escaped.

It all lasted just 10 minutes, with Kardashian's bodyguard arriving to rescue his client after he was alerted.

The suspects were arrested three months after the robbery, through DNA evidence.

But the gold seized was apparently melted down and investigators, who took hundreds of thousands of euros from the suspects when they were arrested, believe that much of the stolen haul was sold in Belgium.

- 'Easy' heist -

Twelve suspects were charged, with 10 going on trial on Monday. One died in March this year and another is to be tried separately for health reasons.

"It wasn't a major armed robbery" but an "easy" heist, said the main suspect, Aomar Ait Khedache, 68, known as "Old Omar". His DNA from the scene helped investigators find him and the co-defendants.

He admitted tying up Kardashian, but disputes investigators' claims that he was the mastermind behind the robbery.

He says he was approached by an unnamed "sponsor" who suggested the scheme on behalf of an "informant" very close to the star, who then gave them the green light.

According to his lawyer, Khedache now has severe hearing and speaking problems and can only express himself in writing.

Presiding judge David De Pas began the hearing by swearing in the stenographers who will transcribe the trial for his benefit.

Another key suspect is Didier Dubreucq, 69, known as "Blue Eyes", accused of being the second person who stormed into Kardashian's room. He denies the charges.

Yunice Abbas, 71, meanwhile stayed in the lobby while the two other men went up to her room, it is alleged.

He controversially sought to capitalise on the crime by writing a book titled: "I Kidnapped Kim Kardashian".

Others on trial are accused of being facilitators and informants, including Gary Madar, the brother of Kardashian's long-serving Paris driver.

He is accused of supplying information about her movements, which he denies.

Despite the "media hype", the trial "must allow for calm debates", warned one of the defence lawyers, Margot Pugliese.

The trial is due to last until May 23.
