ANC MP Nigel Gumede said it was unfortunate people had been encouraged to have fun as close to home as possible but that is where they were being attacked.
He reiterated the call for greater community involvement in the fight against crime.
“People are no longer encouraged to participate in community activities without a cash incentive. Everyone wants work opportunities. If you tell them about community activities, they will ask what’s in it for them,” said Gumede.
“Yes, we can bend God’s will, but are we asking ourselves: what are we learning from these killings? How do we prevent situations like these?”
Ntombifikile Shabalala said her brother Sanele Khenisa was killed in the incident, while her other brother Siyabonga is fighting for his life in hospital.
She said they didn’t know what to do as none of them are working in the family.
Kaunda urged the community to attend court proceedings and call for the suspects to be denied bail so witnesses can feel safe.
Police didn't immediately respond to queries about the arrests.
