At least 24 were killed in multiple attacks across Iraq Wednesday, a police source said.
At least 14 people died and 22 others were wounded in attacks on government installations in Afghanistan's northern province of Kirkuk, the source said.
Militants targeted the city hall, police station and courthouse in Hawijah town.
The dead include three soldiers, seven civilians and four gunmen.
Two car bombs exploded simultaneously near the police station, and that was followed by shelling with a mortar and a ground assault.
In April, 26 people died in Hawijah when police and army troops forcibly broke up a protest in the town square by Sunni Muslims.
The incident unleashed a wave of violence in various parts of the country and protests in the provinces with a Sunni majority.
Ten other people died Wednesday in assorted attacks elsewhere around Iraq, the police source said.
A group of gunmen burst into a home in the Al Shaab neighbourhood in northeastern Baghdad and murdered six members of a family, including three children.
In Al Miqdadiya town, some 120 km north of the national capital, two farmers were killed in another attack.
Also, at least two soldiers were gunned down and another was wounded by an unknown group of gunmen travelling in a civilian vehicle in the vicinity of Al Tayi, 30 km north of Baghdad.
