(CHICAGO) — At least 50 people have been shot, 10 fatally, in Chicago shootings this weekend.

In one shooting, surveillance video captured chaotic moments just after 1 a.m. on Sunday in the city’s Austin neighborhood where seven people were shot, one fatally. Police say it was a gathering that started out as a celebration of life.

In the footage, dozens of people can be seen running away from gunfire, taking shelter behind cars in the 4800-block of West Iowa Street.

Officials say the shooter ran off towards Cicero Avenue. Police continue to investigate.
