Thirteen people have been killed in two separate bomb attacks in Iraq, officials have said.
Two brothers - both policeman - and at least eight of their relatives were reported to have been killed after insurgents bombed a house in Musayyib in the south of Baghdad.
Three people were also killed in Kirkuk in a separate bomb attack.
There has been a rise in attacks in Iraq since US troops left last month.
The Musayyib attack is said to have taken place at 0400 (0100 GMT), when several roadside bombs surrounding the house were detonated.
The dead police officers were named by AFP as Ahmed and Jihad Zuwaiyin. Six children are also believed to have been killed.
Many Shia Muslims live in the Musayyib area.
Four people were reported to be injured and six homes nearby were also damaged.
Police Brigadier General Adil Zain al-Abidine told AFP the attack in the northern city of Kirkuk was caused by a motorcycle bomb parked near a primary school in the city centre.
As well as the three fatalities, five others were also injured.
The violence has come amid a marked deterioration in Iraq's fragile political process.
On Tuesday, at least 13 people were killed and 62 wounded in four separate car bomb attacks in Shia districts of the capital, Baghdad.
Eight died when a bomb blew up close to day labourers waiting for jobs in Sadr City. Minutes later, a blast about 3km (1.9 miles) away killed another two.
Later, car bombs exploded in Shula and Hurriya, killing three.
