Baghdad: Shootings in Baghdad and Iraq’s main northern city Mosul targeting government officials and security forces killed four people on Saturday, officials said.

In the capital, gunmen armed with silenced weapons opened fire on a police patrol in Shaab, north Baghdad, killing two policemen, according to an interior ministry official and a medical source.

An official working at a prison on Baghdad’s outskirts was shot dead by gunmen as he was driving along the Al Qanat highway in east Baghdad, justice ministry spokesman Haidar Sa’adi said. Another prison official, who was in the same car, was wounded.

And in Mosul, 350km north of the capital, gunmen killed a soldier while he was outside his home on leave in the east of the city, security and medical officials said.

Violence is down sharply across Iraq from its peak in 2006 and 2007, but attacks are still common, especially in Baghdad and Mosul.
