It was 7.30 on a hot July morning when the plane came swooping low over the remote ravine. Below, a bridal party was making its way to the groom's village in an area called Kamala, in the eastern province of Nangarhar, to prepare for the celebrations later that day.
The first bomb hit a large group of children who had run on ahead of the main procession. It killed most of them instantly.
A few minutes later, the plane returned and dropped another bomb, right in the centre of the group. This time the victims were almost all women. Somehow the bride and two girls survived but as they scrambled down the hillside, desperately trying to get away from the plane, a third bomb caught them. Hajj Khan was one of four elderly men escorting the bride's party that day.
