Several people have reportedly been shot at a 4 July Independence Day parade near the US city of Chicago, the BBC reports.
The event in Highland Park, north of Chicago, was suddenly halted about 10 minutes after it began, when several shots were heard.
Congressman Brad Schneider, who represents the district, tweeted that he was “hearing of loss of life”.
Five people were seen with blood on them, according to the Chicago Sun-Times newspaper.
The mayor of Highland Park said the festival had been cancelled and asked people to avoid the downtown area.
