Gold and silver prices rose Thursday following news that a passenger plane crashed in eastern Ukraine.
Ukrainian officials said the plane was shot down, though both the government and the pro-Russia separatists fighting in the region denied any responsibility.
The incident brought investors new worries about the region. Tensions have been building between Russia and the West over the conflict in Ukraine and Russia's annexation of the Crimean Peninsula.
Traders moved money into precious metals futures, a traditional safe-haven investment favored in time of geopolitical instability.
Gold for August delivery rose $17.10, or 1.3 percent, to $1,316.90 an ounce. Silver for September delivery rose 36 cents, or 1.7 percent, to $21.34 an ounce.
