At least three people were killed and up to 20 were wounded Thursday in a series of shootings in and near a factory in the Midwestern U.S. state of Kansas.
Law enforcement officials said the gunman was among those killed in the shootings, which occurred at several locations near the city of Hesston.
The gunman, described as an employee at Excel Industries, which makes lawn mower products, was killed by the authorities, Sheriff T. Walton said.
The sheriff said a shooting also took place in the plant parking lot and two other locations nearby.
The shootings came less than a week after authorities said a man opened fire at several locations in Kalamazoo, Michigan, leaving six people dead and two severely wounded.
Walton said a lot was still unknown about the Kansas attacks. He did not explicitly say whether the shootings were related.
"I don't have a lot of answers,'' he said.
Hesston is a community of about 3,700 residents about 35 miles north of Wichita.
