Gold prices fell on Tuesday as investors waited to see whether the U.S. and Iran would consider attending peace talks after renewed tensions over the weekend, while a marginally firmer dollar added to the pressure.

Spot gold was down 0.7% at $4,784.37 per ounce, as of 0615 GMT, extending its fall from Monday when it hit its lowest level since April 13. U.S. gold futures for June delivery fell 0.5% to $4,803.50.
