Christian Aid and partners in the Dominican Republic are mourning the loss of leading human rights activist and long term Christian Aid partner, Sonia Pierre. She died of a heart attack on Sunday 4 December at her home in Villa Altagracia at the age of 48. Sonia was the founder of Mudha -- the Movement of Dominico-Haitian women. She was born in a batey - a poor community that originally housed temporary sugarcane workers - to Haitian parents. From her early teens she began to speak out about the situation of Dominicans of Haitian origin, particularly women, living in the Dominican Republic. Sonia became recognised on the international stage for speaking out against human rights injustices in her country, and in 2010 Hillary Clinton presented her with an International Women of Courage Award. This is archive footage taken of Sonia in 2002. It shows her strength, compassion and determination to speak out for the poorest in her country. She will be sadly missed.
