Such killings are reminiscent of Iraq's worst days of sectarian warfare in 2006 and 2007, when both Shiite and Sunni Muslim death squads roamed the streets and took people from their homes.
Police said the abducted men were killed by gunshots to the head. Authorities found the bodies early today in farmland near the Sunni town of Mishahda, some 30 kilometers north of Baghdad.
Gunmen in four cars snatched the men, who included two army officers and the town's mayor, from their houses late yesterday.
Earlier this week, police found 13 bodies in areas around Baghdad.
"These recent killings show that the fears by many Iraqis that their country is heading to darker days similar to 2006-2007 are true and that the wounds of the past are not healed yet," Baghdad-based political analyst Hadi Jalo said.
"If the government does not take effective measures to stop the sectarian tension and security deterioration, I think that we should expect more such killings."
Two medical officials confirmed the causality figures in the attacks. All officials spoke on condition of anonymity because they were not authorized to talk to journalists.
Violence has been on the rise in Iraq in recent months since a deadly security crackdown in April on a Sunni protest camp north of Baghdad. More than 5,500 people have been killed since.
