Nine people were killed and dozens were hurt when a suspect wearing body armor opened fire outside a bar in Dayton, Ohio, early Sunday before responding officers shot the armed assailant to death less than a minute into the rampage, according to officials.
It was the nation's second mass shooting in less than 24 hours after at least 20 people were slain in El Paso, Texas.
The Dayton Police Department said on Twitter the incident unfolded at 1 a.m. in the city's Oregon District near downtown, but officers were nearby and "were able to respond and put an end to it quickly."
