PARIS (AFP) - A top French appeals court on Wednesday upheld rogue trader Jerome Kerviel's three-year jail sentence over high-risk trading that cost the Societe Generale bank nearly five billion euros (S$9 billion).

But the court cancelled the 4.9 billion euros in damages that Kerviel was ordered to pay, and referred this section of the ex-trader's sentence to another court near Paris to be re-judged.
