Gold prices retreated on Tuesday as an assassination in Turkey and a suspected terror attack in Germany failed to perturb financial markets, says Down Jones.

Gold pulled back 0.36% to $1,133.33 a troy ounce in morning trade in London, as other precious metals also fell. The dollar strengthened, with the WSJ Dollar Index up 0.3% at 93.45, and stocks climbed after U.S. Federal Reserve Chairwoman Janet Yellen in a speech hailed the strength of the graduate employment market.

"[The] gold price is back on the decline having enjoyed three sessions of gains, with risk sentiment doing little to attract investors as the U.S. dollar once again rallies due to the Bank of Japan maintaining accommodative monetary policy and Fed Chair Janet Yellen claiming the U.S. jobs market is at its strongest in a decade," wrote analysts at Accendo Markets.
