Gold slipped to a two-week low on Friday after falling through a key technical level near $1,300 as strong US economic data raised fears the Federal Reserve may start to taper its commodities-supportive stimulus measures. Spot gold fell 1.6 percent to $1,287.56 an ounce by 0642 GMT, bringing losses this week to around 3.5 percent. Gold fell earlier to $1,283.29 - its lowest since July 19. US gold declined $24 to $1,287.10.
