Police in Philadelphia said around 30 officers were injured overnight during protests and riots that were sparked by an officer-involved shooting of a man armed with a knife on Monday. Some in the crowds threw rocks and bricks at police, while some looted or vandalized businesses.
Authorities said that at least one officer, a 56-year-old sergeant, was injured in the unrest. The officer was struck by a pickup truck, breaking her leg, officials said, adding that she suffered other injuries.
