The trial over the Paris robbery that saw Kim Kardashian's multi-million dollar engagement ring stolen has kicked off.

The reality star, who was robbed in her hotel room in October 2016, has said she will appear in person to give testimony in the court proceedings that begin on Monday.

A group of men dubbed the "grandpa gang" were among ten suspects who went on trial on Monday on charges of robbing reality TV star Kim Kardashian at gunpoint and stealing jewelry worth millions of dollars during Paris Fashion Week nearly a decade ago.
