At least 13 people were killed in violence around Iraq on Saturday, while authorities found the decapitated corpses of seven people dumped north of Baghdad in what appeared to be a sectarian revenge killing.
In central Baghdad, two bombs exploded in a parking lot in the Rasheed district shortly before 1:00 pm, killing one person and injuring four others, police Lt Bilal Ali said.
The bombs, hidden in a pair of parked cars, set other cars and a nearby building aflame, Ali said.
The decapitated bodies were found late on Friday in an orchard in the city of Duluiyah, 75 kms north of Baghdad.
Three had been among a group of 17 construction workers kidnapped Thursday while traveling home to the predominantly Shiite town of Balad, police said.
The corpses of the other 14 workers were found earlier on Friday, also all beheaded.
The killings were apparently retaliation for the Wednesday kidnapping of three Sunni Arabs in Duluiyah by a Shiite militia based in Balad, police said.
The three were killed and their bodies burned.
In Diwaniyah, 130 kms south of Baghdad, unidentified gunmen driving by in a car killed teacher Mohammed Muhsin al-Marmadhi as he was leaving his home, police said.
A Shiite family of four were killed in Mahmoudiya, about 30 kilometres south of Baghdad, by unidentified assailants dressed in military-style uniforms who stormed into their house around dawn, army Capt Oday Adul-Ridha said.
Seven other people were killed in a mortar attack near Baqouba, 60 kms northeast of Baghdad, police said.
In Baghdad, a journalist working for government-run TV was killed in a similar drive-by shooting on Friday night.
