Angelina Jolie is back in Africa, traveling for a third time on behalf of the United Nations to monitor the crisis in Darfur, PEOPLE has learned exclusively.
This time, Jolie, the Goodwill Ambassador for UNHCR, the U.N. refugee agency, will not be allowed to actually go to Darfur itself, due to the violent, unstable conditions. On Sunday, Jolie arrived in N'Djamena, Chad, and she's scheduled to visit refugee camps about two miles from the border of Sudan.
Jolie is expected to stay there for a few days, Trevor Neilson, Jolie's political adviser, tells PEOPLE. Her aim with this latest trip is to continue to raise awareness about the continuing crisis, and also see the current conditions – which have deteriorated since her last trip in 2004.
In other Jolie news, the actress has been nominated to join the prestigious Council on Foreign Relations, a think tank of international stalwarts including four Secretaries of State – Condoleezza Rice, Henry Kissinger, Colin Powell and Madeleine Albright. Other members of the group include Alan Greenspan, Tom Brokaw and Richard Holbrooke.
Neilson says the nomination (submitted by a sitting member of the council) was approved, but the board will still need to give its final approval in June. Said Neilson: "Few people are more committed than she is to these issues."
