Shootings and a bombing killed at least six soldiers and five police on Friday, Iraqi security and medical officials said, a day after 33 people were killed in attacks mainly targeting security forces.
At least 50 people, among them 37 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 on Friday 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.
Gunmen also killed two soldiers and wounded three others in an attack on an army checkpoint near Abu Ghraib, west of Baghdad, an interior ministry official said, while a health ministry official put the toll at six soldiers killed and 15 wounded.
And gunmen with silenced weapons shot dead a policeman and wounded another as they drove in Waziriyah in northern Baghdad, the interior ministry official and a medical source from Al-Kindi 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.
