A car bomb targeting police exploded on a crowded Baghdad street Wednesday, killing at least 10 people and wounding 15 others, police said.

Police officer Qahtan Jumaygh said the 8 p.m. blast in the eastern Zaytouna neighborhood (search) was aimed at police patrol cars, but did not injure any policemen.

The explosion also injured 15 other people and damaged a dozen cars in the area.

The blast went off on Al-Rubaei Street when it was most crowded, about 20 yards from a police checkpoint, said one witness, Mohammed Abdullah, who owns an Internet cafe on the street.

Abdullah said he saw "at least 10 civilians killed, including a woman, and five wounded" but that none of the police were hurt. "I just heard a big boom and felt that the ceiling was falling down."
