Gold prices fell more than 1% on Friday and were headed for their worst week since mid-August, dragged lower by a stronger U.S. dollar and worries the Federal Reserve will persist with sharp rate hikes to curb inflation.

Spot gold had fallen 1.3% to $1,643.90 per ounce, down about 2.9% so far this week. U.S. gold futures settled 1.6% lower at $1,649.50.
