CHICAGO: A shootout outside a funeral parlour left 14 people wounded Tuesday in Chicago, as President Donald Trump threatens to send federal agents to a handful of US cities led by Democratic mayors.

The incident started when occupants of a vehicle "began firing at attendees of a funeral. At that time the attendees of the funeral exchanged fire," Chicago deputy police superintendent Eric Carter told reporters.

Shootings have become breathtakingly normal this summer across the United States. A total of 63 people were shot and 12 killed over the weekend in Chicago in ongoing gun violence, according to local media.
