The two actors visted Pakistan after the earthquake in 2005
Hollywood stars Angelina Jolie and Brad Pitt have donated $1 million to help Pakistanis displaced by fighting, the UN refugee agency says.
More than two million people have been uprooted since the army began fighting Taliban militants in Pakistan's Swat region earlier this year, the UN says.
Ms Jolie has visited Pakistan three times since becoming a goodwill ambassador for the agency in 2001.
The two actors made the donation through their charitable foundation.
Ms Jolie and Mr Pitt - who are partners - have set up the foundation to help counter humanitarian crises.
In 2005, the two visited survivors of an earthquake which devastated parts of northern Pakistan.
They travelled aboard a helicopter carrying food, blankets and plastic sheets.
The quake left more than 73,000 people dead and millions homeless.
