At least three people have been killed and four others injured in separate attacks targeting Iraqi officials and security forces.
A female judicial investigator and a police sergeant were shot dead in the northern town of Tuz Khurmatu on Wednesday while a member of an anti-al-Qaeda militia was shot dead and another was wounded in a gun attack on a checkpoint in Samarra, north of Baghdad, AFP reported.
Three other militiamen were also wounded in a bomb attack targeting their vehicle in Baladruz town, 75 kilometers north of the capital.
Bomb attacks and shootings have increased in Iraq over the past weeks.
On Tuesday, six Iraqi soldiers were killed and two others were injured in two explosions targeting a military convoy on the main road between the towns of al-adhaim and Tuz Khurmatu.
However, July was the bloodiest month in Iraq in almost two years. Official figures put the number of people killed in attacks in July at 325, the highest monthly death toll since August 2010.
