Idinga kuphela amayintshi angu-246 okulungiswa okuqondile kumayadi angu-1,000, kanye namayintshi angu-40 okulungiswa okuvundlile kumayadi angu-1,000 emoyeni wamamayela amahlanu ngehora. Umzuliswano osindayo futhi ushaya ngamandla engeziwe kumabanga amade, okwenza kube maningi amathuba okuthi kukhubaze okuqondiwe. Ububanzi obuyindilinga obungu-.300 bungamayadi angu-1,300.
