19 injured in mass shootings in Tucson, Minneapolis early Sunday

In Minneapolis, nine adults were shot outside a nightclub in the city's Uptown district early Sunday, interim Police Chief Bill Peterson told reporters. Two of the male victims had potentially life-threatening injuries. Officers arrived in less than a minute and found multiple victims and a large crowd, Peterson said. He called the shooting "a brazen act of violence in a crowded entertainment district where innocent people were placed at tremendous risk."

Tucson Mayor Regina Romero said the incident was "another serious and senseless act of gun violence." A shooter "began shooting in a crowded area striking nine people before being stopped by a Tucson Police Officer," she said. She credited firefighters and police with stabilizing the victims and said she hoped they would recover. Romero blamed "easy access to guns" and "Arizona's weak gun safety laws" for continuing to put residents at risk.

Former Arizona congresswoman Gabby Giffords, who survived an assassination attempt in 2011, said she was "heartbroken" by the Tucson shooting. "Too many lives have been changed forever because of America's gun violence crisis, in my hometown and across the nation," she said.
