At least 12 masked gunmen opened fire inside a restaurant in the northern border city of Ciudad Juarez, killing eight, police officials said Saturday.
Chihuahua state prosecutor's office spokesman Alejandro Pariente says the gunmen arrived at the seafood restaurant Friday evening in three cars, approached a group of people and opened fire.
Pariente says no arrests have been made.
The attack comes days after police found the bodies of seven men who were killed in a school soccer field in an upscale neighborhood of Ciudad Juarez, across the border from El Paso, Texas.
The homicides were the latest of hundreds of killings in the city, where drug violence has taken a heavy toll during Mexico's nationwide crackdown on drug cartels that supply U.S. consumers.
