Protesters in several Chinese cities have gathered to demand a boycott of French products and denounce campaigns for Tibetan independence. Hundreds of people demonstrated in cities including Beijing, Wuhan, Hefei, Kunming, and Qingdao - often outside stores of the French chain Carrefour. Passions ran high, but the protests were closely patrolled by police. Protesters say they are angry at the scale of protests that accompanied the Olympic torch relay in Paris. They have also denounced French President Nicolas Sarkozy's refusal to confirm whether he will attend the opening ceremony of the Games. Pictures from the central city of Wuhan showed large crowds congregating outside a Carrefour supermarket.
