Halloween shooting last night in Chicago that left kids dead and about 20 wounded in two separate shooting attacks in the U.S. cities of Kansas City and Chicago, police said.

At least 13 people were shot in a drive-by shooting in Chicago on Monday night, police said, including a 3-year-old and two other children.

Between five and seven people were shot and one was killed in a shooting at a home in Kansas City, where about 70-100 teens were partying on Monday night, city police chief Karl Oakman said.

Some individuals unknown to the homeowners started shooting when they were asked to leave, Oakman told reporters.

Police had earlier said as many as 14 people were shot, but said in a later statement that 13 had been shot.

The violence at the intersection of California Avenue and Polk Street at around 9:30 p.m. in the area of Garfield Park was partially captured on surveillance video, police said.

“We know it’s a drive-by. We know it happens in just a few seconds,” Brown said. “It begins and then it’s over, about three seconds the car is pulling out after driving by and shooting randomly, really, into the crowd.”
