A wave of violence killed at least 24 people in Iraq on Tuesday, including several civilians who died when five car bombs went off in Baghdad, security and medical officials said.
The attacks were the latest in a surge of unrest that has left more than 4,200 people dead this year, according to an Agence France Presse tally.
Six policemen were killed in the ambush and two were seriously wounded.
Late Tuesday evening, five car bombs exploded in various parts of Baghdad , including the centre and northeastern suburbs of the capital, killing at least 16 people and wounding 50 more. Most of those killed were civilians, security sources reported to AFP.
Also in Baghdad, a provincial officer was shot dead and a soldier was killed by an explosive device in Mosul, AFP added.
An unspecified number of suicide bombers, wearing explosive belts, attacked a police station west of Baghdad, in Fallujah, and engaged in a gun battle with security forces, according to AFP.
Three of the bombers died when their explosives detonated while the fourth was killed by police, the sources said, adding that 12 policemen were wounded, AFP reported.
