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

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.

Police opened fire on their buses, killing six people.

Twenty-two police officers are being held in connection with the shooting.

Witnesses said the most of the survivors - all trainee teachers - were bundled into police vans before disappearing.

Some had gone into hiding and contacted their relatives after several days, still fearing for their lives.
