On 15 November 2008, around 9:00 a.m., approximately fifteen masked Israeli settlers from the illegal outpost of Havat Ma'on attacked three Palestinian shepherds who were grazing their flocks in a valley south of the outpost. The settlers came running down from a ridge above the shepherds, hurling rocks. The shepherds were able to get their flocks away before the rocks injured them.
During the incident, the settlers were able to steal two of the shepherds' donkeys. The settlers killed one donkey with a knife wound in the chest area. They slashed another across the throat, but the donkey survived.
