One-year-old boy killed in Chicago drive-by shooting

A drive-by shooting caused the death of a one-year-old boy here on Saturday afternoon, and wounded his mother, local media reported.

The tragedy occurred when the 22-year-old mother was driving home on the city's south side. The perpetrator slowed down to run next to her car and fired around eight shots, hitting the baby in the chest and grazing the mother's head, police said.

Gun violence is frequent in the third largest U.S. city. A week ago, a three-year-old boy was shot dead in a car while traveling with his father.

Reports said local police vowed to catch the killers in the two cases, and investigations are underway with no arrest made yet.
