Angelina Jolie was thanked for "doing incredible things" at the Woman in the World summit last night by a Rwandan genocide survivor who introduced her to the stage.

The 36-year-old actress, who is a United Nations Goodwill Ambassador, spoke about the plight of Somali refugees at the event at the Lincoln Centre in New York, and was introduced by Rwandan genocide survivor Sandra Uwiringiyimana.

Taking to the stage, Sandra thanked Angelina for "taking justice into her home and hands and doing incredible things."

During her address, Angelina told the story of Dr. Hawa Abdi, who runs a medical camp in Somalia which is now being overrun by militants and has been nominated for the Nobel Peace Prize for her work.

She said the story "illuminates the nightmare of tens of millions around the world, the internally displaced and the ones homeless within their homelands."

She added: ''It is, right now, Friday morning in Somalia. In a few hours, 400 human beings are about to become, once again, displaced.''

Other speakers at the three-day summit include politician Hillary Clinton and actress Meryl Streep.
