Mexico City, Nov 13 (IANS/EFE): The Inter-American Commission on Human Rights (IACHR) has agreed to assist the Mexican government in clearing up the case of 43 students who went missing after being detained by police.

Meanwhile, protests about the case continued in the country.

Mexican authorities Wednesday agreed to IAHCR's terms of assistance and those of the parents of the students who disappeared on Sep 26 in the southern town of Iguala after being handed over by the local police to a criminal gang.

The accord, signed in Mexico City, calls for the IACHR to oversee the creation of a group of experts who will provide assistance and technical verification concerning the actions of the government which has faced criticism from the families and many Mexicans.

The Mexican foreign ministry said the signing of the agreement was one of the pledges by President Enrique Peña Nieto to the parents during a meeting last month.

The ministry also referred to the meeting between the Undersecretary for Multilateral Affairs and Human Rights, Juan Manuel Gómez Robledo, and the UN High Commissioner for Human Rights, Zeid Ra'ad Al Hussein, in Geneva Wednesday.

Al Hussein offered the services of his office to help clarify the facts in the case and ensure justice.

While the ramifications of the case have now extended overseas, in Mexico the protests are becoming more radical.

In the state of Guerrero, where Iguala is located, some 600 teachers of the State Coordinator of Education Workers of Guerrero (Ceteg) set fire to the facilities of the Comptroller of the Secretariat of Education and the Guerrero state assembly.

The parents of the missing students have distanced themselves from the violent actions of Ceteg, an organisation involved in road blocks and attacks on government and political party offices to protest education reform enacted by Peña Nieto in 2013.

Violent protests have also broken out in other parts of Mexico such as Michoacan state where hundreds of students blocked access to the airport in Morelia, the state capital.

Prosecutors announced that the charred human remains collected from a dumpster and a river in the town of Cocula, near Iguala, have been sent for genetic analysis to the University of Innsbruck in Austria.

In testimony to investigators, members of the criminal gang involved in the disappearance, said the students were killed and their bodies incinerated.

Mexican officials continue to maintain the status of the students as missing until the arrival of the results of the analysis from the only laboratory that was able to extract genetic material from two of the bones found.
