Gunmen dressed as police kidnapped 19 people working for a money changer and two household appliance shops in Baghdad today, police said.
The abductions happened in three separate areas in northern and central Baghdad. It was not immediately clear whether the three incidents were related.
Yesterday gunmen also kidnapped 16 employees of Baghdad trading company Al Saeed Import Export in the upscale Mansour district of the capital.
Earlier Baghdad police found the bodies of 14 men who had been shot in the head, a police source said.
Some of the men were blindfolded. Their identities are unknown but they were found in the Hay al-Adil district in the mainly Sunni west of the Iraqi capital.
US and Iraqi officials say dozens of people are being killed daily in sectarian violence that has increased since the bombing of a major Shi'ite shrine a month ago in Samarra.
It also emerged today that Kurdish forces detained an Arab doctor in the disputed northern Iraqi city of Kirkuk because they believe he treated Sunni Arab insurgents, security officials said.
