Mexico student hunt finds mass grave near Iguala

A mass grave has been found on the outskirts of the Mexican town of Iguala, where 43 students went missing on 27 September.

Forensic experts are trying to establish if the bodies found in a pit are those of the missing students, who were last seen being forced into police vans.

The group had travelled to the area to take part in a protest over teachers' rights but six people were killed when police opened fire on their buses.
