A bombing and a shooting killed four soldiers and four police on Friday, security and medical officials said a day after 33 people were killed in attacks mainly targeting the security forces.
At least 47 people, among them 34 members of the security forces, have been killed in violence in the first three days of August, which have seen a number of attacks on soldiers, police and anti-Al-Qaeda militiamen, and their facilities.
A roadside bomb targeted an army patrol east of Dhuluiyah, killing four soldiers, among them a major, and wounding four others, an army captain and a medical source said.
Insurgents had attacked a military base near Dhuluiyah on July 23, killing at least 15 soldiers and wounding two more.
And gunmen opened fire on a police checkpoint in Baquba, killing four policemen and wounding two more, a police major and Dr. Ahmed Ibrahim of Baquba General Hospital said.
Official figures put the number of people killed in attacks in July at 325, the highest monthly death toll since August 2010.
While violence has decreased compared to its peak in 2006 and 2007, attacks remain common across Iraq. There were attacks on 27 of the 31 days in July.
