A bombing and a shooting attack in Iraq's city of Samarra have killed four soldiers and four police officers, security and medical officials said.

Friday’s killings in the city north of the capital Baghdad come one 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 near Dhuluiyah killing four soldiers, among them a major, and wounding four others, an army captain and a medical source said.

Fighters 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 local doctor said.

Official figures put the number of people killed in attacks in July at 325, the highest monthly death toll since August 2010.
