Investing.com - Gold futures were higher on Tuesday, as safe-haven demand was boosted amid ongoing geopolitical concerns in Ukraine, Iraq and Gaza.
On the Comex division of the New York Mercantile Exchange, gold for December delivery tacked on 0.5%, or $6.50, to trade at $1,317.00 a troy ounce during U.S. morning hours.
Prices held in a narrow range between $1,306.90 and $1,317.80 an ounce. A day earlier, gold prices declined 0.04%, or 50 cents, to settle at $1,310.50.

In Ukraine, a Russian convoy of 280 trucks carrying humanitarian aid set off on Tuesday amid Western warnings against using help as a pretext for an invasion.
Ukraine has claimed that 45,000 Russian troops have amassed on its border, while NATO warned that there was a "high probability" Moscow would intervene militarily in the country's east, where government forces are closing in on pro-Russia separatists.
Meanwhile, in Iraq, Haidar al-Abadi, the deputy speaker of parliament, was named as the new prime minister on Monday in place of Nuri al-Maliki, but Maliki has refused to step down and deployed special forces in Baghdad.
Maliki said the decision was a "dangerous violation" of the constitution and vowed to "fix the mistake".
U.S. President Barack Obama said the naming of Abadi was an important step for Iraq towards rebuffing Islamic State militants.
The U.S. recently began air strikes targeting jihadi militants from the Islamic State insurgent group in the northern part of the country in an effort to protect Iraqi civilians from the uprising as well as U.S. personnel in the country.
Elsewhere, a 72-hour ceasefire which began late on Sunday evening between Israel and Hamas in Gaza held for a second day, following a month of violence in the Hamas-ruled territory.
Gold is often seen as a haven investment in times of geopolitical uncertainty.
