The other two shootings – both in South Carolina – left a total of 18 people with gunshot wounds, rekindling calls among supporters for substantial gun control legislation. In Pittsburgh, police said fire-detection equipment prompted police to head to Suismon Street, where at least 10 people were shot at around 12.30pm on Sunday. First aid transported several of the victims to a hospital, including two 17-year-old boys who were later pronounced dead by doctors. Others who were shot but survived went on their own walks to the hospital. There were at least 50 shots fired at the house by several people who had been dragged into some sort of clash, police said. A handful of other attendees who were injured but were not shot had been cut and broken bones as they jumped out of the windows of the house in a desperate attempt to reach safety, the investigators added. Authorities did not immediately release the arrests, although Pittsburgh Police Chief Scott Schubert promised that his officers would “do everything possible.” [they] can take those responsible “. “That should not have happened,” Schubert told a news conference this afternoon. “We are sick of it.” The short-term rental provider Airbnb issued a statement saying that the person who had rented the house had now been banned from using the service for life. The man violated the policy of the company that bans parties, said the statement of the Airbnb spokesman, Ben Bright. “We share the Pittsburgh community’s outrage over this tragic armed violence,” Breit said in a statement. “Our hearts go to all who were [affected]including loved ones who have lost their lives, injured victims and neighbors ”. Investigators found the violence erupted at a party at a short-term rental party, which attracted about 200 guests, most of whom were under the age of 18, police said in a statement. Officials did not immediately release the names of the boys killed. Meanwhile, also early Sunday, gunfire erupted at a nightclub in Hampton, South Carolina, injuring nine people. None of the injuries reported at Cara’s Lounge, about 80 miles west of Charleston, were fatal, officials said, without immediately announcing any arrests in the case. The bloodshed occurred about 90 miles north of, and a few hours later, a separate shooting at a mall in the South Carolina capital, Columbia, left nine with bullet wounds. The injured ranged in age from 15 to 73, and a man – 22-year-old Jain Price – was jailed after the shooting on charges of carrying a pistol illegally. Price’s guarantee was set at $ 25,000 on Sunday afternoon. Violence in Pittsburgh and South Carolina erupted as many American Christians prepared to attend church to worship on Easter Sunday. It also happened after at least two other high-profile shootings elsewhere in the US. A shooting in central Sacramento on April 3 killed six people and injured 12 others. Another fired 10 shots at a New York subway on Tuesday. Police have arrested suspects in both the Sacramento and New York shootings.
