MEXICO CITY, Safar 5, 1436, Nov 27, 2014, SPA -- Mexico's embattled President Enrique Pena Nieto said on Thursday he would propose constitutional changes to simplify the country's chaotic policing structure following the abduction and apparent massacre of 43 trainee teachers, Reuters reported. Pena Nieto has been under growing pressure from protesters to end impunity and brutality by security forces since the 43 students were abducted by corrupt police in the southwestern city of Iguala on the night of Sept. 26. The government says local police handed over the students to a drug gang, which apparently murdered them and then incinerated their bodies. In a speech to an assembly of political leaders, Pena Nieto said: "Mexico cannot continue like this." -- SPA 23:23 LOCAL TIME 20:23 GMT www.spa.gov.sa/w
