Mohammed Munim, 35, was working at an Interior Ministry office that issues government ID cards to residents in Baghdad's Shiite Sadr City neighborhood when a car exploded outside.
He was hit by shrapnel in his neck and back.
Mr Munin told the Associated Press from his hospital bed:
It was a thunderous explosion.
The only thing I remember was the smoke and fire, which was everywhere.
