Albertina Sisulu, 92, a veteran of South Africa's antiapartheid movement who was married to Nelson Mandela's mentor, has died.

African National Congress spokesman Brian Sokutu, confirming the death Thursday, said Ms. Sisulu "dedicated all her life to the ANC and to the defeat of apartheid and ushering in of constitutional democracy in South Africa."

Walter Sisulu, who died in 2003, spent 25 years in custody on Robben Island alongside Mandela, whom he had brought into the ANC. Albertina Sisulu was left behind to raise the couple's five children. She spent months in jail herself and her movements were restricted.

Ms. Sisulu, trained as a nurse, campaigned against apartheid and for the rights of women and children. She was a leader of the United Democratic Front, a key antiapartheid coalition in the 1980s. She also was a leader in the ANC and the ANC's women's wing.

She lived to see her children take prominent positions in postapartheid South Africa. Daughter Lindiwe Sisulu is defense minister. Son Max Sisulu is speaker of the National Assembly. Albertina Sisulu also served four years in parliament. - AP
