Jolie and Pitt to adopt from South America

Angelina Jolie and Brad Pitt are keen to adopting a child from South America - but they are finding it difficult to negotiate the complicated adoption laws.

The couple already have three adopted children, Maddox, seven, from Cambodia, Pax, four, from Vietnam, and Zahara, three, from Ethiopia. They also have three biological children Shiloh, two, and baby twins Knox and Vivienne.
