Mass shootings across the US mar the first weekend of summer

The first weekend of summer brought a tragic yet familiar pattern for American cities wracked by gun violence. Mass shootings over the weekend left dozens dead or wounded at a party in Alabama, an entertainment district in Ohio and a grocery in Arkansas. It was the second straight weekend that saw an outbreak of mass shootings and across the U.S. It all left mayors in several cities marred by the shootings pleadings for help from the state and federal governments. Police in Montgomery, Alabama, say hundreds of rounds were fired at a crowded party early Sunday where nine people were wounded.
