CIUDAD JUAREZ, Mexico (AP) – Police say 20 people have been killed in less than three days in this crime-ridden border city’s latest wave of violence.

State police spokesman Cesar Ramirez says a father and son who were killed at their home while sleeping were among the victims. A third victim was a man whose body was cut up in pieces and dumped in an empty lot.

Ramirez says that this year alone more than 500 people have been killed in Ciudad Juarez, across the border from El Paso, Texas. The city is home to the powerful Juarez drug cartel and has been among the hardest-hit cities in an explosion of violence across Mexico.

Arm yourselves El Paso.
