Hollywood star Angelina Jolie (search), who is also a goodwill ambassador for the U.N. High Commissioner for Refugees (search), met with Pakistan's prime minister in Islamabad on Wednesday, a foreign ministry statement said.

During her meeting with Prime Minister Shaukat Aziz (search), she thanked him for hosting Afghan refugees, it said.

Jolie has visited refugee camps in some countries since 2001 when she became a goodwill ambassador for the agency. She will meet Afghan refugees during her three-day in Pakistan, officials say.

Her visit came two days after a census conducted by Pakistan with UNHCR assistance showed that just over 3 million Afghans were living in Pakistan. Millions of Afghans have fled to Pakistan to escape wars and poverty at home since 1979 when Soviet troops invaded Afghanistan.

The actress won a supporting-actress Oscar for 1999's "Girl, Interrupted." She is best known for her role in the "Lara Croft Tomb Raider" action movies, one of which includes scenes filmed on the Greek island of Santorini.
