Philadelphia: Two police officers injured in second Fourth of July shooting in US

Two Philadelphia police officers have been shot as thousands of people celebrated a Fourth of July concert and fireworks show.

Video posted on social media show hundreds of people in the crowd scattering in panic after shots were fired.

The shooting near the Benjamin Franklin Parkway came hours after a gunman on a rooftop opened fire on families at a Fourth of July parade in the Chicago suburb of Highland Park, where six people were killed and over 36 were wounded.

Both officers in Philadelphia were in stable condition with non-life threatening injuries, CBS3 Philadelphia said, citing the police department. Police were searching for the attacker.

The gunfire broke out late on Monday near the Philadelphia Museum of Art on the final day of a festival with a large number of people watching a fireworks show after a concert.

“There is a security incident on the Benjamin Franklin Parkway,” emergency authorities said, referring to the shooting.

Police instructed people in surrounding buildings to shelter in place.

“I didn’t hear the shots, but the cops were like, ‘Run, run, run,’” one woman told an NBC affiliate.

One officer sustained a graze wound to the head and the other a gunshot wound to the right shoulder, according to NBC10.
