Chinese authorities slaughtered over 20,000 birds at a poultry market in Shanghai on Friday as the death toll from a new strain of bird flu mounted to six, spreading concern overseas and sparking a sell-off in airline shares in Europe and Hong Kong. All the 14 reported infections from the H7N9 bird flu strain have been in eastern China and at least four of the dead are in Shanghai. REUTERS/Carlos Barria (CHINA - Tags: HEALTH ANIMALS) - RTXY9B3
