A lorry bomber killed more than 100 people in central Baghdad on Saturday, one of the bloodiest days in the Iraq conflict so far.
More than 200 people were wounded in the bombing, which targeted a crowded market.
Hospitals were inundated with the dead and injured and their anxious relatives.
The blast came after a wave of car bombings hit the northern city of Kirkuk on Saturday.
Seven bombs - one said to be a suicide attack - went off in different parts of the ethnically mixed city over a two-hour period, killing at least five people.
Rebwar Abdullah of the Kurdish Democratic Party visited one bomb site under heavy guard - among the targets were the offices of the two Kurdish political parties.
A car bomb also killed one civilian in Mahmoudiya, south of Baghdad. There has been an upsurge in sectarian violence in the past year in Iraq - with dozens of people killed every day.
