Gold prices touched the lowest in more than one week on Thursday, as the dollar stood firm on rising US Treasury yields, with investors focusing on who would replace Janet Yellen as the next chair of the Federal Reserve. US President Donald Trump is set to make a decision in the "coming days" on Yellen, who is also one of the five candidates being considered for the job. Spot gold eased 0.1 percent to $1,279.25 an ounce as of 0646 GMT after earlier hitting its lowest since Oct. 9 at $1,276.22. US gold futures for December delivery were down 0.1 percent at $1,281.40 per ounce.
