Mandela's grandson speaks after return from Israeli detention over flotilla

A group of South African activists, including Nelson Mandela's grandson, Nkosi Zwelivelile "Mandla" Mandela, arrived in Johannesburg on Wednesday (October 8) morning after being detained by Israel for their participation in the Global Sumud Flotilla. Mandla Mandela, 51, said he and his group were held in an Israeli prison for six days before being released via Jordan. South African President Cyril Ramaphosa called Israel's interception of their boats a "grave offense".
