Shawdesh Desk:

At least 10 people were killed and more than two dozen wounded in four shootings across the United States this weekend, as lawmakers struggle to respond to the country’s long-running epidemic of gun violence.

The shootings came after a spate of mass killings that have sparked renewed calls for reform of the nation’s gun laws.

An eruption of violence in Chattanooga, Tennessee on Sunday resulted in 14 people being shot, including two killed, while another person died and two more were injured after they were struck by vehicles fleeing the scene, police chief Celeste Murphy said, adding “several” victims remained in critical condition.

The pre-dawn incident occurred near a nightclub.

In Philadelphia on Saturday, two men and a woman were killed when multiple people opened fire on a crowd at a popular South Street nightlife area.

Philadelphia Police Commissioner Danielle Outlaw said one of the victims got into a fight with another man, which could have been the cause of the shooting.

The two others were “innocent bystanders,” she told reporters.

Gun attacks are common in America, but the shock felt over recent mass shootings at a grocery store in Buffalo, New York and an elementary school in Uvalde, Texas — which killed 10 and 21 people respectively — have spurred cries for action.
