BAGHDAD, Aug. 5 (Xinhua) -- Seven people were killed and seven others injured Sunday in separate gunfire and bomb attacks in northern and central Iraq, the police said.
In Iraq's northern province of Nineveh, gunmen using pistols fitted with silencers attacked a police checkpoint in Bab-Sinjar district in western the provincial capital city of Mosul, some 400 km north of Baghdad, killing three policemen, a provincial police source told Xinhua on condition of anonymity.
In a separate incident, a gunman threw a hand grenade on a police checkpoint in al-Kornesh area in central Mosul, killing two passers-by, the source said.
The policemen at the checkpoint opened fire on the attacker and shot him dead, the source added.
In central Iraq, a car bomb went off in Baghdad's northern district of Qahirah near the convoy of Brigadier General Mohammed Ghazi, head of the personal protection directorate in the Interior Ministry, killing a passer-by and injuring the officer and two of his bodyguards, an Interior Ministry source anonymously told Xinhua.
Three civilians were also wounded by the attack, the source said.
In addition, Sheikh Abdulla al-Nadawi, a tribal leader, was wounded when a sticky bomb attached to his car detonated while he was driving in al-Kasrah district in northern Baghdad, the source added.
Violence is still common in the Iraqi cities despite the dramatic decrease since its peak in 2006 and 2007, when the country was engulfed in sectarian killings.
