Mexican President Felipe Calderon has condemned an attack on a Chihuahua drug rehabilitation facility that left 19 people dead.
Mr. Calderon issued a statement from Johannesburg where he attended the opening of the World Cup. He said the attack by more than 24 armed men reinforces the conviction to fight criminal gangs that carry out such "barbaric acts."
On Thursday, a gang of gunmen killed 20 people in another northern Mexican town known for drug-related gang warfare. Authorities say some of the 18 men and two women killed in the series of shootings in Madero were bound in handcuffs.
An estimated 23,000 people have been killed in drug-related violence in Mexico since President Calderon began a crackdown on the drug cartels after taking office in December 2006.
