An anti-tank mine was planted in a stream and when the vehicle crossed the water there was a very heavy blast.
There are still some bodies lying under the water but we are facing problems in retrieving them because they are traditional people who do not want unknown males to touch the bodies of their women.
The number of casualties and the damage suggest that there could have been more than one landmine but we have not confirmed that at this stage.
There were women and children in the vehicle and we are trying to get details of how many.
We believe 20 of the dead were women and children, six were men and another is unknown. It is difficult to get the exact toll because many of the bodies were blown to pieces.
