CHICAGO – Two men who opened fire on a crowd of people reunited for a baby shower, injuring six people, including two children, may have acted in retaliation for a previous gang conflict, announced Sunday. police.

Authorities have only "bits and pieces of information" about what happened at the family reunion in Chicago because witnesses do not cooperate, a police spokesman said, but investigators hope that the severity of the injuries inflicted on the children will push somebody to talk.

"It's a very tragic incident. You have two young children, one 8-year-old and one 10-year-old, who clings to life, "said Chicago Police spokesman Anthony Guglielmi.

At least a dozen people were gathered in front of a house decorated with balloons for the baby shower when two armed men approached on foot and started firing around 18:30. Saturday, said Guglielmi.

An 8-year-old boy was shot in the chest and back and a 10-year-old girl in the leg. Both children were in critical but stable condition. Their names have not been revealed.

Four other people were also affected: three men aged 23 to 48 and a 29-year-old woman. The woman was hospitalized in critical condition and the two younger men were in stable condition.

The condition of the eldest man was unknown and Guglielmi stated that it was not clear if the injured woman was perhaps the pregnant person.

People rushed inside the house when the shooting started. Children playing in the yard would have begun to pile up while they were trying to get through the door.

"We were trying to get the kids out of the way, they were going to be crushed," said Richard Nix, whose grandson was taking the shower, at the Chicago Tribune. "It was nothing but children in front of the house, sitting on the porch. They were playing and the shooting was triggered.

"This is part of a larger conflict taking place in this region," Guglielmi said.

Another shootout occurred Sunday morning about three blocks from the house where the gunfire broke out, he said, but it was unclear whether there was any link.
