PARK TOWNSHIP, Michigan (AP) — A fireworks explosion in western Michigan killed one woman and left nine other people with injuries ranging from critical to minor, the Ottawa County Sheriff’s Department said.

The explosion happened Monday, but a news release from the department did not say whether it occurred during an organised July Fourth public event. Deputies and ambulances responded to Main Street in Park Township shortly after 11 pm for a report that a firework exploded injuring several people, the release said.

A 43-year-old woman from the city of Holland died at the scene, the sheriff’s department said. Nine other people were taken to area hospitals.

Several area homes and vehicles also were damaged, the release said.

The explosion is under investigation.

Park Township has a population of about 18,000. It’s on the Lake Michigan shore about 30 miles (48 kilometers) southwest of Grand Rapids.

The US Consumer Product Safety Commission reports that in 2022, 10,200 people were treated at emergency rooms and 11 deaths were blamed on fireworks. About three-quarters of injuries happened in the period around the Fourth of July.

In Allegan County, just south of Ottawa County and about 30 minutes earlier, an errant firework exploded in or near a crowd gathered for the Allegan July 3 Jubilee show. Allegan Police Chief Jay Gibson told WWMT-TV that an errant mortar fired off during the show.

There were no immediate reports of injuries. But it was enough to cause panic.
