Bari baje kw’ihwaniro ryataziriwe ngo “Inkuru nziza y’ibihe bidahera.” Ni ryo hwaniro mpuzamakungu rya mbere ryabereye muri Endoneziya.

Abavukanyi baragize ingorane nyinshi mu gutegura iryo hwaniro. Ikibanza ryari kuberamwo cahindutse incuro zitatu kubera ibirori vyo guhimbaza umusi mukuru wo kwikukira. Kubera ko amahera yari yataye agaciro bigatuma leta igwiza na kane ibiciro vyo kwiyunguruza, hari abashitsi baciye bahindura uburyo bwo kwiyunguruza. Umuvukanyi umwe yagize urugendo rw’imisi itandatu kugira ashike kw’ihwaniro. Abashitsi 70 b’i Sulawesi bagize urugendo rw’imisi itanu mu bwato bupakiye abantu isinzi, bicaye ku masaso yabwo.

Kuri iryo hwaniro, abavukanyi bo muri Endoneziya barahimbawe no kubonana n’abavukanyi bo mu bindi bihugu harimwo na Frederick Franz be na Grant Suiter bo mu Nama Nyobozi. Umushitsi umwe yavuze ati: “Abavukanyi bo ng’aha barahimbawe cane, baguma bitwengera.”

Abantu barenga 750 ni bo bitavye iryo hwaniro, 34 na bo barabatizwa. Ronald Jacka agira ati: “Iryo hwaniro ryaratumye abantu benshi baza mu kuri. Ryaratumye abavukanyi bo ng’aho bongereza umwete mu ndimiro.”
