Jolie said the numerous poor Afghan families she met during her visit Wednesday and Thursday were indicative of the "human spirit at its best," People magazine reported Friday.

"The courage, resilience and quiet dignity of returnee families rebuilding their lives against the kind of adversity few of us can imagine shows the human spirit at its best," Jolie said.

The 33-year-old Hollywood star serves as a goodwill ambassador for the United Nations High Commissioner for Refugees.

People said Jolie has urged the international community to offer additional aid to those returning refugees to help them survive the upcoming winter.
