UNHCR spokesman Ali Bebe says the Hollywood star arrived Monday and is to visit Jordan’s first tent city for Syrian refugees on Tuesday morning.

Jolie will be accompanied by U.N. refugee chief Antonio Guterres and Jordanian Foreign Minister Nasser Judeh on the visit to the Zatari camp, which hosts about 27,000 Syrians displaced by the 18-month conflict.

Jordan has sheltered more than 185,000 Syrian refugees — the largest number in the region.

The UNHCR in April promoted Jolie from serving as its goodwill ambassador to special envoy due to her work for the agency. Jolie has contributed $5 million to U.N. efforts aiding refugees worldwide.
