Gunmen killed a Sunni Arab tribal leader and a government official in central and northern Iraq on Wednesday, the police said.
In west of Baghdad, gunmen wearing military uniforms before dawn stormed the house of Shiek Ali Dayeh al-Fahdawi, chieftain of Albu-Fahad tribe, in the town of al-Khaldiyah, some 80 km west of Baghdad, a source from the operations command of Anbar province told Xinhua on condition of anonymity.
The attackers dragged Fahdawi and his brother away from his house and shot them dead, the source said.
Insurgent attacks continue in the once volatile Sunni Arab area in west of Baghdad that stretches through Anbar province to Iraq's western borders with Syria, Jordan and Saudi Arabia.
The province cities and its vast desert area has been relatively calm for more than three years after Sunni tribes and anti-U.S. insurgent groups turned to cooperate with the U.S. troops and Iraqi security forces against al-Qaida network in Iraq.
In northern Iraq, unidentified gunmen in their car shot dead Khawla al-Sab'awi, female government official, in front of her house in al-Wahda neighborhood in eastern Mosul, some 400 km north of Baghdad, a local police source told Xinhua on condition of anonymity.
Nineveh province has long been a stronghold for insurgent groups, including al-Qaida militants. Its capital city of Mosul is one of the country's most restive cities.
