In Mexico, three arrests have been made in the state of Zacatecas after an armed group kidnapped seven teenagers on Sunday. After days of searching, the bodies of six of them were found on Wednesday. One teen survived and is being treated in the hospital. Three of the teenagers were cousins; the rest were classmates. They were abducted while they were together for a sleepover. The killings have sparked outrage in a community where fighting between rival drug cartels has led to a soaring number of murders and disappearances. Many have blamed the U.S.-backed war on drugs for exacerbating drug cartel violence in Mexico.
