On 13 September, after SAO Krajina forces captured Hrvatska Kostajnica and Hrvatska Dubica, the conflict shifted north, where a new line of control was established south of ZNG-controlled Sunja and Novska.
Armed Serbs burnt Croat-owned houses in the village of Cerovljani, just to the north of Hrvatska Dubica, on 13 September and once more on 21 September.
