Meanwhile, crowds gathered across Mexico on Tuesday to mark the third anniversary of the disappearance of 43 students from the Ayotzinapa teachers’ college in the southern state of Guerrero. The students went missing on September 26, 2014, after being attacked by local police. International experts say the Mexican military and federal police also played a role in the students’ disappearance. The parents of the missing students arrived in Mexico City for the march in buses filled with supplies for victims of the earthquake.
