With gold recently hitting highs of nearly $1,400 per ounce, an armed raid on a row of goldsmiths' shops in Baghdad has left at least nine people dead.
The gunmen used hand grenades and small arms to kill three gold shop owners in a market in the Mansour district of western Baghdad, an Interior Ministry source said.
Reuters reports that when the attackers emerged from the shops they were met by soldiers and police.
Two gunmen, two police officers, a soldier and four civilians died in the shootout, two security sources said.
Security officials say some of the insurgent groups that took up arms after the 2003 US-led invasion that toppled Saddam Hussein have turned to crime to finance their operations, attacking banks, gold markets and jewellery shops.
Authorities said they did not yet know whether the Mansour suspects were insurgents or a criminal gang.
Iraq has seen a big drop in violence since Washington sent thousands of extra troops and built alliances with tribal leaders to battle a stubborn insurgency, but attacks are still common in Baghdad and ethnically and religiously mixed areas north of the capital.
