bosniaks and croats began to leave the municipality because of a growing sense of insecurity and fear caused by intensifying serb propaganda. the municipal newspaper kozarski vjesnik started publishing allegations against the non-serbs. the serb media propagandised the idea that the serbs had to arm themselves. terms like ustasha (ustaše), mujahideen (mudžahedini) and green berets (zelene beretke) were used widely in the press as synonyms for the non-serb population. radio prijedor disseminated propaganda insulting croats and bosnian muslims. as one result of the takeover of the transmitter station on mount kozara in august 1991 by the serbian paramilitary unit the wolves of vučjak, tv sarajevo was cut off. it was replaced by broadcasts from belgrade and banja luka with interviews of radical serb politicians and renditions of serb nationalist songs, which would previously have been banned.
