BAGHDAD - Iraqi security forces set up checkpoints on Monday in the Dora neighborhood southeast of Baghdad, where media reports have said three US nationals were kidnapped on Friday, witnesses said.
Two Iraqi army helicopters were also seen hovering over the district while police SUVs were patrolling the streets.
The US State Department said on Sunday it was working with Iraqi authorities to locate Americans reported missing, without confirming that they had been kidnapped.
Dubai-based news channel Al Arabiya reported on Sunday that three US nationals had been kidnapped in Dora on Friday. Citing its own sources, it said the Americans were "contractors or trainers" employed by US companies at the Baghdad airport
