Gold regained some strength on Thursday after a drop in the previous session attracted bargain hunters, but a strong dollar and fading expectations of more monetary easing in the United States made the metal vulnerable to more selling. Spot gold hit an intraday high at $1,648.41 an ounce and stood at $1,643.59 by 0703 GMT, up $1.49.
Gold extended losses and fell more than 2 percent on Wednesday after the Federal Reserve offered no clues on further easing. US April gold rose $1.30 an ounce to $1,644.20 an ounce.
