American civil rights activist Reverend Jesse Jackson has visited the home of fallen South African liberation icon Winnie Madikizela-Mandela. He told journalists outside the home on Friday that the US Congress had passed a resolution to honour Madikizela-Mandela's life."She never stopped fighting, she never stopped serving," Jackson said.He said Madikizela-Mandela had taken South Africa's fight for liberation across the globe, explaining they knew very little about the human rights violations until she became the face of the struggle."We didn't know [what was happening with] Mandela, but we knew he was alive because his heart was Winnie's heart."

Soweto residents have joined throngs of people who've lined the streets outside her home to form a guard of honour.The liberation icon, better known as the Mother of the Nation, will be laid to rest at Fourways Memorial Cemetery on Saturday.
