Cape Town – A grandmother, a teenager, and an 8-year-old boy were killed in an apparent gang retaliation attack in Nyanga, Cape Town on Tuesday.A man died in hospital later that night after he was shot on the same street where the granny lived, Western Cape police spokesperson Constable Noloyiso Rwexana said on Wednesday.The killings started when a 43-year-old man was shot in his car in Sibini Avenue, Zwelitsha, Rwexana said.He died on arrival at hospital. A few hours later, three people went to a house in the same street, looking for an 83-year-old woman’s grandson. They shot and killed the grandmother.Rwexana said the shooters then made their way to a home in Kuqala Avenue. There they shot and killed an 8-year-old boy and a 15-year-old girl. A 7-year-old girl was shot and injured. She was taken to hospital.Nyanga CPF chairperson Martin Makhasi said a gang war was in full force in Nyanga, Gugulethu and New Crossroads."It has been happening for a very long time. Retaliation killings are affecting these areas," he told News24 on Wednesday.He said it was ironic that the issue had been raised with the new provincial police commissioner, Lieutenant-General Khombinkosi Elvis Jula, at a meeting a few days ago.Residents had told him that they did not see the same "vigour and response" to gangs in their area as in neighbouring communities.'It seems black lives are cheap'Makhasi said Tuesday night’s bloodshed was the latest in a string of shootings since the beginning of the month."These people are armed, not with 9mm guns, but even with machine guns."The killing of innocent people had angered him."The granny was killed in the comfort of her own house. She was never a gangster. We can shout at the top of our voices, but really, it seems black lives are cheap."Nyanga councillor Khaya Yozi said police were aware of a group of young men terrorising people with guns. Sometimes they targeted people in broad daylight."This is a problem we are facing here. We are going to have a meeting with the Nyanga CPF. People will take the law into their own hands."Rwexana said they were investigating four murders and one attempted murder.Anyone with information on the whereabouts of the killers was asked to contact Nyanga detectives on 021 380 3320 or Crime Stop on 08600 10111.
