The first large-scale mass executions began on the afternoon of 13 July 1995 in the valley of the River Cerska, to the west of Konjević Polje. One witness, hidden among trees, saw two or three trucks, followed by an armoured vehicle and an earthmoving machine proceeding towards Cerska. After that, he heard gunshots for half an hour and then saw the armoured vehicle going in the opposite direction, but not the earthmoving machine. Other witnesses report seeing a pool of blood alongside the road to Cerska that day. Muhamed Duraković, a UN translator, probably passed this execution site later that day. He reports seeing bodies tossed into a ditch alongside the road, with some men still alive.
