Relatives of the 113 victims of the Air France Concorde crash near Paris are commemorating the first anniversary of the disaster.

More than 200 family members, most of them from Germany, are to lay commemorative plaques and attend a religious service at the Saint Sulpice Church in Paris. The BBC's Jon Sopel reports
