A string of bomb and mortar attacks was launched in and near Baghdad, killing about 30 people, injuring scores and leaving scenes of devastation.
Many civilians were among the dead and injured - some were able to walk away from the wreckage.
Others had to be carried to hospital by friends and colleagues.
Friends and relatives gathered at local hospitals - but for some the news was of the loss of their loved ones.
Passers-by were left in shock as emergency services rushed to the attack sites.
Two Baghdad markets were among the sites chosen for attack - including the old Isterbadi market in the mainly Shia suburb of Kazimiyah.
At the second market, Haraj, survivors watched as the bloodstained wreckage was cleared away.
One bomb ripped through a minibus, causing devastation and killing at least three passengers.
Residents had hoped the huge security clampdown would increase safety on the streets of the capital.
