Mexican President Enrique Pena Nieto has replaced the country's national security chief, 1 ½ months after top drug lord Joaquin "El Chapo" Guzman escaped from a maximum security prison.

Pena Nieto did not mention the escape Thursday when he announced that National Security Commission head Monte Alejandro Rubido was leaving the Cabinet. His replacement is Renato Sales, the current head of the anti-kidnapping commission.

Guzman's July 11 escape proved a major embarrassment to the government.

Pena Nieto named current foreign relations secretary Antonio Meade as the head of the social development department.

Current tourism secretary Claudia Ruiz Massieu will take over the country's top diplomatic post.

Changes were also made in the education agriculture and environment departments. Former attorney general Jesus Murillo Karam left the cabinet.
