US police authorities say three people have lost their lives and 11 others were wounded after gunfire broke out on a popular street in the US state of Pennsylvania, only two days after another fatal shooting incident in Iowa state.
Police Inspector D. F. Pace said that two men and a woman were killed in the Philadelphia attack on Saturday, adding that officers responding to the incident “observed several active shooters shooting into the crowd.”
Pace asserted that officers had fired at one of the shooters, though it was unclear whether the person was hit.
Local media outlets reported that no arrests had been made.
Pace said two handguns were recovered at the scene, and that police would have to wait until morning to review surveillance footage from nearby businesses that were closed on Saturday night.
Pace described the investigation as “fluid,” saying there were still “a lot of unanswered questions.”
On Thursday, a man shot and killed two women outside Cornerstone Church, east of the city of Ames, while a program was in progress inside.
Nicholas Lennie, chief deputy of the Story County Sheriff’s Office, said the attack appeared to be “an isolated, single-shooter incident”.
Authorities have not yet identified a motive for the attack, and the relationship of the attacker with the victims was not immediately known.
One person was separately killed and eight others wounded early Saturday in a shooting amid a crowd of people at a strip mall northwest of downtown Phoenix, police said.
Sergeant Andy Williams told reporters that nine people, whom he characterized as young adults, were taken to hospitals, including three with critical injuries, after the 1 a.m. shooting (1800 GMT Friday) sent people running near 10th Avenue and Hatcher Road.
In an interview posted by ABC 15 television station, Williams said no suspects were immediately identified and no arrests were made while authorities pieced together witness accounts.
The United States has been shaken in recent weeks by the mass shootings that killed 10 Black residents in upstate New York, 19 children and two teachers in Texas, and two doctors, a receptionist, and a patient in Oklahoma.
The shootings have renewed a push for federal legislation to address gun violence, but efforts aimed at some reforms remain an uphill battle despite some progress in bipartisan discussions.
