A bomb blew up a kerosene tanker truck in Baghdad's Sadr City neighborhood on Saturday, killing 35 people, police said.
Another 38 people were wounded by the 10 a.m. (0600 GMT) blast in the sprawling Shiite slum. People frantically carried survivors from the narrow muddy street to ambulances, and hauled away bodies in blankets.
Dhiyaa Ali a 24 year-old college student, said he heard the explosion from his nearby home and ran to the street to help people. He said bodies and blood were everywhere.
"I went into the flames just to get anyone left out of the fire," told AP. "I saw a mother holding her child, both of them burned and dead."
The bomb was hidden in a barrel near the tanker, where scores of people were waiting to buy fuel, said police Col. Saad Abdul-Sada.
