Authorities say two people were killed and four others wounded in a shooting in north Philadelphia early on Labor Day during a violent holiday weekend that has seen seven other homicides and a number of other shootings and stabbings.

Police said officers responding to scene shortly before 1 a.m. Monday found two victims on the street. One, a 33-year-old woman, was pronounced dead at the scene minutes later. A 19-year-old man taken to a hospital in a private vehicle with multiple gunshot wounds was pronounced dead shortly before 5:30 a.m. Monday. Two others — a 23-year-old man and a 55-year-old man — were in critical condition, and a man and a teenager were listed as stable.
