On 7 August, two VRS air force jets attacked a village in the Nova Gradiška area, just north of the Sava River—the international border in the area. The CAF bombed an ARSK command post, a storage facility and several tanks near Bosanski Petrovac. CAF jets also struck a column of Serb refugees near Bosanski Petrovac, killing nine people, including four children. On 8 August, the CAF performed its last combat sorties in the operation, striking tanks and armoured vehicles between Bosanski Novi and Prijedor, and two of its MiG-21s were damaged. The same day, UN military observers deployed at Croatian airfields claimed that the CAF attacked military targets and civilians in the Dvor area, where refugee columns were mixed with ARSK transporting heavy weapons and large quantities of ammunition. Overall, the CAF performed 67 close air support, three attack helicopter, seven reconnaissance, four combat air patrol and 111 transport helicopter sorties during Operation Storm.
