Twelve people, including a three-year-old child, have been shot at a park in the US city of Chicago.
Ten adults and the three-year-old were transported by Fire Department ambulances after the attack in the city's Back of the Yards neighbourhood, said Fire Department Deputy District Chief James Mungovan.
A 12th victim was believed to have driven himself to hospital, a source said, citing preliminary information.
Chicago Fire Department officials said the child was in critical condition. Two other victims were also in critical condition, officials said.
Four were in fair-to-serious condition, and four were in good-to-fair condition, according to the Fire Department.
A witness at the scene said three police officers carried the child to an ambulance.
"I didn't hear no sounds," from the child, he said.
The attack took place about 10.15pm on Thursday (1315 AEST Friday) and fire officials initiated an emergency plan, sending at least 10 ambulances to the scene.
A total of at least 11 people were shot, including the three-year-old, who was shot in the face, according to a source.
A witness, Julian Harris, told the Chicago Sun-Times that dreadlocked men fired at him from a grey sedan before turning toward Cornell Square Park and firing at people in the area. He said his three-year-old nephew was wounded in the cheek.
"They hit the light pole next to me, but I ducked down and ran into the house," he said. "They've been coming round here looking for people to shoot every night, just gang-banging stuff. It's what they do."
Authorities said no one had been taken into custody in connection with the shooting.
Francis John, 70, said she was in her apartment when the shooting occurred. She said went down to see what was going on and "a lot of youngsters were running scared".
She said she was surprised by what had happened, saying she has lived in the neighbourhood for 30 years.
Ambulances were still responding about half an hour after the shootings took place, as injured people were still being brought out of the park on stretchers. About 60 police officers were on the scene.
