A gunman perched on a rooftop has opened fire on families waving flags and children riding bicycles during an Independence Day parade near the US city of Chicago, killing at least six people and wounding 36 others.
The shooting in Highland Park, a community of about 30,000 residents some 40km (25 miles) north of Chicago, Illinois, caused panicked mayhem on Monday as hundreds of marchers, including parents with strollers, fled the scene in terror.
