Twenty-four shootings and five murders took place across Chicago over the weekend amid a spike in gun violence in the third-largest US city, police say.
Two children were hurt when gunmen opened fire at a gathering on Saturday.
The most recent fatal shooting occurred on Sunday morning. A 52-year-old man was found dead with a bullet wound to the head.
Last year Chicago recorded 561 murders, more than the two biggest US cities – New York and Los Angeles – combined.
There were 44 murders in Chicago in the first two months of 2019.
The two children shot on Saturday were injured while attending a baby shower in the South Side. They are in a critical but stable condition.
Police say the shooting could have “stemmed from an ongoing gang conflict” in the area.
Later on Saturday, a 19-year-old man was shot dead in the south of the city as he was standing outside with a friend.
Shots were fired at him from a vehicle, the Chicago Sun Times reported. The friend is said to be in a good condition.
On Sunday morning, a 32-year-old man was shot in the back, also in the South Side. He was taken to hospital where he was pronounced dead.
Chicago police say that as of 1 March, they had seized more than 1,600 illegal guns this year. The figures equate to one illegal gun taken off the street every 53 minutes.
