Ohio: Update: The mayor of Dayton, Ohio, has weighed in on a mass shooting that killed nine people and injured at least 16 others.

Mayor Nan Whaley tweeted that she was "heartbroken" around 6am on Sunday, around five hours after the active shooter situation began in Dayton's historic Oregon District.

She thanked first responders and said officials would share updates when they had more information.

Dayton police have yet to identify the suspected shooter, who was shot to death by responding officers.

According to the AP/USA Today/Northeastern University database, the Dayton shooting is the 22nd mass killing and sixth public mass shooting in the U.S. in 2019. It came just hours after 20 people were killed in an El Paso, Texas, shooting.

Nine people were killed in a mass shooting early Sunday in Dayton, Ohio, police said, adding that the assailant was shot dead by responding officers.

The incident occurred shortly after 1am in the popular bar and nightlife Oregon district of the city, Police Lieutenant Colonel Matt Carper said.

"The shooter is deceased. There are nine others also deceased. At least 16 others went to area hospitals with injuries," the police department said on Twitter.

Miami Valley Hospital spokeswoman Terrea Little said 16 victims have been received at the hospital, but she couldn't confirm their conditions. Kettering Health Network spokeswoman Elizabeth Long said multiple victims from a shooting had been brought to system hospitals, but didn't have details on how many.

The Oregon District is a historic neighborhood near downtown Dayton that's home to entertainment options, including bars, restaurants and theaters. Police have not said where in the district the shooting took place.

The FBI is assisting with the investigation.

An earlier report said multiple people were shot early Sunday in an entertainment district in Dayton, Ohio, according to local news reports.

The police were called to East Fifth Street in the city's Oregon District shortly after 1am, the local news media said. The Dayton Police Department said on Twitter that it was investigating a shooting in the area but provided no additional information.

An employee at Ned Peppers, a bar on the street, wrote in a post on Instagram that "all of our staff is safe and our hearts go out to everyone involved as we gather information."

Information was not immediately available on the number of people wounded or the status of the gunman.

The shooting came less than a day after a gunman in El Paso, Texas, left at least 20 dead and 26 others wounded inside a Walmart store. Last week, a gunman killed three people and wounded 13 others in a shooting at a garlic festival in Gilroy, California.
