MEXICO bowed to pressure on Tuesday to relaunch its investigation of last year’s disappearance of 43 teaching students, who are believed to have been murdered.

The government accepted recommendations made by the Inter-American Commission on Human Rights but will not allow a group of independent experts to directly question military personnel about the case.

Eber Betanzos, deputy prosecutor for human rights at the federal attorney general’s office, said his entity “completely” accepts a report by the five experts.

One expert, Colombian Angela Buitrago, said the relaunched search would be carried out “with a strategy based on lines laid out by the group, including the use of technology, mapping of clandestine graves and other locations and establishing a path of action agreed upon by the families.”

The students disappeared in September 2014 after being detained by police in the city of Iguala in the southern state of Guerrero.

Prosecutors claim the students were handed over to a drug gang, killed and incinerated at a rubbish dump, though the victims’ relatives and independent observers have cast doubt on the official version of events.
