Security forces have mounted some of the biggest operations targeting militants since the 2011 withdrawal of American troops.
Prime Minister Nuri Al Maliki has nevertheless vowed to press on with the campaign in a bid to combat the country’s worst bloodshed since 2008, with more than 3,500 people killed since the start of the year and the interior ministry describing Iraq as a “battleground”.
Monday’s attacks concentrated in Mosul, a city in northern Iraq that has long been one of the country’s most violent areas.
Three workers in a carpentry shop were shot dead by militants, while two policemen were gunned down in a pre-dawn attack on a checkpoint, officials said.
Gunmen also killed a man from the small Kurdish sect known as Shabak outside his house in Mosul.
The 30,000-strong Shabak community is present in 35 villages in the Nineveh province near the border with Turkey, with many members wanting to join the autonomous Kurdish region of northern Iraq.
The community was persecuted under ousted Iraqi dictator Saddam Hussein, and after the 2003 US-led invasion of Iraq they were targeted numerous times by Al-Qaeda.
Violence has markedly increased in 2013, with more than 3,500 people killed since the beginning of the year, according to an AFP tally.
The relentless bloodshed is the worst in five years and has raised fears Iraq could slip back into the all-out sectarian violence of 2006-2007.
Security forces have been carrying out wide-ranging operations in multiple provinces including Baghdad, after brazen July assaults on two prisons, claimed by an Al Qaeda front group, that freed hundreds of inmates.
