Former Roman Catholic Bishop Edward Daly, who tended victims of Northern Ireland's Bloody Sunday massacre, has died aged 82.

The Catholic Diocese of Derry says Daly died peacefully on Monday.

British paratroopers opened fire on a Catholic protest march in Londonderry on Jan. 30, 1972, killing 13. The killings helped fuel Northern Ireland's sectarian violence, in which some 3,000 people died.

Daly became a hero by administering last rites to victims on the streets of the Catholic Bogside district. A photo of the priest waving a blood-stained white handkerchief as he tried to help a fatally wounded victim become one of the event's iconic images.

Daly served as a priest in the city from 1962, and was Bishop of Derry from 1974 to 1994, stepping aside after suffering a stroke.
