In Mexico, President Enrique Peña Nieto has visited the city of Iguala for the first time since 43 students disappeared from the city after being attacked by local police more than one year ago. During the visit, Peña Nieto avoided meeting with the families of the disappeared students, and he made only passing reference to the students during a military ceremony on Wednesday. The visit comes only days after a team of independent investigators held a news conference criticizing the Mexican government for continuing to block their inquiry into the students’ disappearance. Investigator Claudia Paz y Paz said the team was looking into the link between the disappearance and drug trafficking routes between Iguala and Chicago.

Claudia Paz y Paz: “For us, it is fundamental to deepen the line of investigation of the transfer of heroin from Iguala to Chicago. It has advanced, but we believe that it is necessary to continue with all the tasks that we have proposed within this line to clarify the events.”

Claudia Paz y Paz is the former attorney general of Guatemala.
