Angelina Jolie has donated $1 million to the U.N. refugee agency to help Afghan refugees.

Jolie, who is a goodwill ambassador for the U.N. High Commissioner for Refugees, has given the money as part of the agency's appeal for $268 million to meet the humanitarian needs in and around Afghanistan.

"This significant contribution from a concerned young American reinforces my belief that, despite the trauma of recent events in her country, a strong sense of humanitarian responsibility toward innocent civilians suffering in far-off places continues to animate the spirit of caring individuals everywhere," High Commissioner Ruud Lubbers said in a statement Wednesday.

Jolie, 26, went to Pakistan in August to visit some of the more than 3.5 million Afghans living in camps there and in Iran.

With the threat of U.S. retaliation attacks following the Sept. 11 terrorist attacks in New York and Washington, refugee officials are preparing for the arrival of up to 1.5 million more people.
