A gunman has killed five co-workers at a brewing company in the US state of Wisconsin, before taking his own life.
The suspected gunman was an employee at the Molson Coors plant in Milwaukee.
More than 1,000 employees were at the complex when the shooting occurred, the city's police chief Alfonso Morales told reporters.
Police responded to reports of a shooting and when they arrived at the scene they found the body of the suspected gunman, a 51-year-old employee at the plant.

The entire Molson Coors property was placed under a security lockdown for several hours following the gunfire as police swept each building to rule out any further threats or victims.
"We can now say that the scene is secure. All employees who were on scene have been allowed to go home," Mr Morales told reporters.
Mr Morales said the attack was confined to the Molson Coors complex west of downtown, a facility known to locals as the old Miller brewery, and that "no members of the general public were involved".
Miller beer is one of the company's leading brands and Mayor Tom Barrett said the plant has been part of the city for 165 years.
US President Donald Trump referred to the gunman as a "wicked murderer" and called the gun violence "a terrible thing".
"Our hearts go out to the people of Wisconsin and to the families," he said.
At a news conference earlier in the evening, the Milwaukee Mayor Tom Barrett described the shooting as "an unspeakable tragedy".
"There were five individuals who went to work today just like everybody goes to work. They thought they were going to work and return to their families. They didn't, and tragically they never will," he said.
Following the attack, the company advised employees in an email that the gunman had been located in or near a second-floor stairwell near a packaging facility, The Milwaukee Journal Sentinel reported.
Hours later at Spitfires on State, a tavern a few blocks from the shooting scene, patrons made solemn toasts to Miller, an iconic Milwaukee brand.
A small group of employees, still wearing their protective gear from their shift earlier in the day at the brewery, huddled together inside the bar.
Last year saw 417 mass shootings in the United States, according to the Gun Violence Archive, the highest annual number since the nonprofit research group started keeping a tally in 2013.
GVA defines a mass shooting as any in which at least four people, excluding the perpetrator, are shot.
