At least 35 people have been killed and 50 wounded in a suicide car bombing in Abu Saydah, northeast of Baghdad.
The bomber drove a car into a tent set up by a Shi'ite family to receive condolences after the death of a relative, some 65km from the Iraqi capital.
Mourners in Iraq traditionally erect a tent outside their home to receive condolences from relatives and friends.
Meanwhile, five US soldiers have been killed in two separate bomb attacks near Baiji, north of Baghdad.
The deaths bring the number of US military personnel killed in Iraq since the March 2003 invasion to 2,086.
13 dead in Baghdad bombing
Officials in Baghdad say at least 13 people have been killed by a car bomb in a largely Shi'ite district in the south of the Iraqi capital.
Some 20 people were wounded in the attack which took place in a crowded street market.
Police said the attack was not carried out by a suicide bomber.
It came as more than 50 Iraqi politicians from across the country's sectarian divide gathered for reconciliation talks in Cairo, aimed at easing bloodshed that has plagued Iraq since the US-led invasion in 2003.
In a second blast this morning, a suicide bomber in a car attacked a police convoy in central Baghdad, wounding two officers and eight civilians, police said.
Yesterday, 77 people were killed and more than 80 wounded in twin suicide bomb attacks on mosques in the town of Khanaqin, near the border with Iran in northeastern Iraq.
Twin suicide car bombs also detonated outside a popular hotel in Baghdad, destroying an apartment building and killing six people. More than 40 were wounded.
Separately, US President George W Bush has used a speech at a military base in South Korea to reject mounting calls to set a deadline for the withdrawal of American troops from Iraq.
