Gold advances 2.3% for week, its second week of gains.
Gold futures soared on haven-related buying Friday after a U.S. airstrike killed a top Iranian military commander, sparking a vow of vengeance from Tehran and a stock-market selloff.
Gold for February delivery on Comex added $24.30, a gain of 1.6%, to settle at $1,552.40 an ounce, a level last seen on Sept. 4 when bullion closed at $1,560.40 an ounce. March silver advanced 10.5 cents, a gain of 0.6%, to settle at $18.15 an ounce.
