At least 32 people, including two journalists, were killed across Iraq on Saturday in attacks that included a shooting and bombings, dpa reported.
Assailants shot dead a reporter and a cameraman working for the private al-Sharqiya TV channel in the northern city of Mosul, the broadcaster said.
Al-Sharqiya did not say why the journalists were targeted.
Mosul, 400 kilometres north of Baghdad, is among the most ethnically diverse and dangerous cities in the country.
The Defence Ministry said soldiers killed seven gunmen after they received intelligence about their whereabouts in the northern part of the country.
Infantry and military jets destroyed five hideouts in sand dunes near the northern city of Biji, which lies on the main road to Mosul.
In Tikrit, 12 people were killed and 32 wounded when a car bomb went off in front of a cafe south of the city, 170 kilometres north of Baghdad, police officials said.
Eleven people were killed and 22 injured in separate bombings across Baquba, a city located 60 kilometres north-east of Baghdad.
There has been a sharp rise in attacks in Iraq in recent months, raising fears of a return to the violence that pushed the country to the brink of civil war in 2006 and 2007.
According to UN estimates, 979 people were killed in September, making it one of the deadliest months in the country in the last five years.
