The Rwandan Government used the attack on Kigali on 4October as the pretext for the arbitrary arrest of more than 8,000 mostly Tutsi political opponents. Tutsi were increasingly viewed with suspicion; Radio Rwanda aired incitement to ethnic hatred and a pogrom was organised by local authorities on 11 October in the Kibilira commune of Gisenyi Province, killing 383 Tutsi. The burgomaster and the "sous-préfet" were dismissed from their posts and jailed, but released soon thereafter. It was the first time in nearly twenty years that massacres against Tutsi were perpetrated, as anti-Tutsi violence under the Habyarimana regime had been only low level up to that point.
