The 37-year-old actress flew down to Erbil on Sunday after meeting Iraqi returnees from Syria and senior government officials Saturday in Baghdad, reported CNN online.
She discussed the situation of Syrian refugees in Iraq with Foreign Minister Hoshyar Zebari at his office in Baghdad. They also talked about the Iraqi government's efforts to meet the daily needs of refugees, the ministry said in a statement.
Jolie also met with officials from the Iraqi ministry that deals with displaced people.
She has recently visited refugee camps in Turkey, Lebanon and Jordan to highlight suffering and the need for international humanitarian assistance.
While at the Zaatari refugee camp in Jordan on Tuesday, Jolie spoke of the horrors that children, many of them orphans, have witnessed in Syria.
"I am grateful to Jordan and the border countries for saving the lives (of those) who are dying in Syria. It's an extraordinary thing. We encourage the international community to support the people here until one day they go back home," she said.
