Can South Africa find answers to the death of 21 teenagers?

Africa Daily - A podcast by BBC World Service

Police in South Africa are examining how 21 teenagers died at a drinking tavern in the city of East London. The youngest to have died on Saturday night was just 13 years old. The minimum drinking age in South Africa is 18, so they should not have been in the spot. There were no visible injuries on the bodies of the victims, so police have said that a crush is unlikely. There have been reports that the victims may have been poisoned. Whatever happened in the early hours of Sunday morning, people in South Africa are keen to make sure it can not happen again. #AfricaDaily
