The actress made the comments in her role as special envoy of the U.N. High Commissioner for Refugees, while visiting a Kurdish refugee camp in Dohuk, northern Iraq.
The camp is currently home to tens of thousands of Yazidis and other refugees who have been forced to abandon their homes in Mosul, which has been invaded by the Islamic State.
Angelina said:
'Since I was last here in Iraq, another two million people have been forced from their homes. The brutality of the conflict and the speed and scale of the displacement has shocked the world and help has come, but not nearly enough.
'It is past time for leaders on all sides to find a common ground and a way to move forward.'It is not enough to defend our values at home, we have to defend them here in the camps and in the informal settlements across the Middle East and in the ruined towns of Iraq and Syria.''We are being tested here as an international community and so far, for all of the immense efforts and good intentions, the international community is failing.
'The people I met today need to know that we will be with them, giving them the support they need to survive for every day that they are displaced.
'And above all, they need to know that one day they will be able to go home and that there will be an end to this suffering.'
