Hollywood actor Angelina Jolie, who has promoted humanitarian causes throughout the world feels the needs of Haitian orphans devastated by a quake are “almost incalculable“.

The 34-year-old beauty, a UN Goodwill Ambassador said before the Caribbean nation’s cataclysm, SOS Villages had been raising more than 300 orphaned or abandoned children and cared for 4000-plus poverty-stricken kids and families in Haiti, US magazine reported.

“That was before the earthquake, now the needs for orphaned children are almost incalculable,” Jolie said in a statement.

The ‘Original Sin’ star insists the organisation has been working nonstop in Haiti to find shelter, food, medicine, trauma counselling and more for children and families.

“As a long time supporter of SOS, I have visited many of these unique villages personally. I can vouch for their commitment and care for the children. As the Haiti situation unfolds, and we all focus in on ways to help these desperate children -- I ask you to please learn more about and consider supporting SOS Children’s Villages,” Jolie added.
