The US embassy in Baghdad has confirmed that "several" Americans have been kidnapped in the city.
BBC News quotes a state department official as saying:
"We are working with the full co-operation of the Iraqi authorities to locate and recover the individuals."
US officials did not say how many were held or where they were seized, but an official in Baghdad said three CNN contractors were missing.
AFP said an Iraqi police colonel said on condition of anonymity that three Americans and an Iraqi translator were kidnapped in southern Baghdad.
In January, a group of Qatari hunters, including members of the ruling family, was kidnapped in the Iraqi desert, and their whereabouts are still unknown.
