Gold price falls even amid terrorist attacks in Brussels

Gold prices fell to a four-week low and the dollar's strength slowed, despite a suitable buying zone following Tuesday's attacks in Brussels.

Precious metals fell more than 2% in morning trading in London and 2.4% to $ 1,218.60 an ounce on the New York Mercantile Exchange.

Gold is under pressure as the Federal Reserve moves closer to raising interest rates. Philadelphia Fed President Patrick Harker said the central bank should consider another hike next month if the U.S. economy continues to improve, while Chicago Fed President Charles Evans also said he expects two more rate hikes this year.

Higher interest rates will boost the dollar and could make gold more expensive for investors who hold other currencies.
