Actress and UN ambassador Angelina Jolie has appealed to the international community to aid the plight of millions of Afghan refugees living in Pakistan.
Jolie said it was very difficult for refugees to return home
The Oscar-winning star spent four days in refugee camps and said help was needed to "shoulder the burden of this part of the world".
She said war-battered Afghanistan needed more funds so refugees could return home and rebuild their lives.
Some refugees have been in Pakistan for more than 25 years.
"I met a woman who was about to get on a truck with a small baby," she said.
"I do not know how she is going to survive, and how she will be able to make a living, to find food, to find health care. So it is very, very difficult, but many people are moving back."
An estimated 2.3m Afghans have returned to their country under a UN-supported repatriation scheme since the fall of the hardline Taleban regime in late 2001.
But more than three million more remain in camps and cities in Pakistan.
Jolie, who won a best supporting-actress Oscar for 1999's Girl, Interrupted, became a goodwill ambassador for the United Nations High Commissioner for Refugees in 2001, and has visited refugee camps throughout the world.
She met Pakistan's Prime Minister Shaukat Aziz last week and thanked his country for taking in three million refugees.
