Gold prices fell for a second straight session on Thursday to again finish at their lowest level in about five weeks. The precious metal failed to find support from a pullback in U.S. Treasury yields, as strength in the U.S. dollar and gains in the stock market helped dull demand for gold. June gold declined by $4.90, or 0.4%, to settle at $1,317.90 an ounce-the lowest for a most-active contract since March 20.
