"It started out apparently with an active shooter at the Fifth Third tower, there was an officer intervention and from there now it's just victims and things like that," a police officer told a local CNN affiliate.

A Cincinnati city councilman called the incident "terrible" on Twitter and asked for prayers for the city.

"Terrible shooting incident in the heart of our city this morning. Multiple shot, and tragically there are fatalities. Details still emerging. Pray for our city," P.G. Sittenfeld wrote.

"Update (but still fluid): 5 shot, including shooter, who now being told is in critical but not deceased. Police & Fire doing exemplary job," he added. "What a sick, tragic way for this day to begin. The scourge of gun violence leaves only loss."
