Kulabo abathanda imininingwane eyengeziwe, kunendatshana enikezelwe ku-.
Eminyakeni yakamuva, abezindaba baye babhala ukuthi imiphakathi yendawo isabela kanjani ekufikeni kweqhwa. Abantu abaningi babengakaze balibone iqhwa ekuphileni kwabo, futhi ukufika kwalesi simo kuye kwadonsa ukunaka kwabo bobabili abantu bendawo kanye nezivakashi. Inkundla yezokuxhumana igcwele izithombe namavidiyo aqopha lo mcimbi ongajwayelekile, okhombisa abantu bejabulela indawo yasebusika endaweni ebingalindelekile.
