At least 14 people, including two children and a teenager, were shot in a drive-by shooting in western Chicago on Halloween night on Monday, but there were no immediate reports of fatalities, police said.

The injured were in various conditions, with several in critical and others non-life threatening, Chicago Police Superintendent David Brown said in a press briefing.

One more person was injured after being struck by a vehicle at the site of the shooting.

Citing preliminary information, Mr Brown said one vehicle was involved in the shooting, but there were possibly two shooters.

The police did not identify the offenders or have any details of the motive, he told the briefing.

According to police statistics more than 2,352 people had been shot in Chicago by September this year. Homicides year-to-date in 2022 were up some 35 percent compared to 2019 figures by September.
