Mexico missing students: Mass grave found near Iguala

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

It is not clear whether 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, in the state of Guerrero, to take part in a protest over teachers' rights.

The BBC's Will Grant says the families are "extremely angry" at what they see as a lack of action to find their missing relatives.
