PARIS (Reuters) - Twenty people go on trial in Paris on Wednesday suspected of involvement in a jihadist assault on Nov. 13, 2015, the most deadly attack ever seen in peacetime France, in which 130 were killed and hundreds injured.

A specially-built courtroom and additional rooms where the hearings will be broadcast are ready to admit 2,000 people daily at a tribunal in central Paris for a trial of unprecedented proportions that is set to last nine months.
