PHOTOS: Angelina Jolie visits Syrian refugees in Jordan

Her eyes welling up with tears, actress Angelina Jolie said on Tuesday she heard "horrific" and "heartbreaking" accounts from Syrian refugees who fled the civil war in their country to find shelter in a camp just across the border in Jordan.

The Hollywood star and UN refugee agency's special envoy spoke as she visited the Zaatari camp, which hosts about 30,000 Syrians displaced by the 18-month conflict that has so far claimed at least 23,000 lives, according to activists.

"I am very concerned, the world is very concerned," Jolie said during her high-profile visit aimed at focusing international attention on the plight of Syrian refugees and attracting more funding to help them. "What is very heartbreaking is when Syrian people ask you why you think no one is able to find a solution for them."

"What they described on the ground, hearing it from them is so horrific," she said, adding that the children's stories were especially moving. "When you meet so many innocent people and civilians, the people of Syria are asking who is on their side. 'Who is going to help us as the months go on?'"

The actress also said some of the refugees expressed fears "there will be no more of us" left in Syria as the relentless bloodshed grinds on.

Jolie also met separately with Syrian refugee women and toured the sprawling tent city in the company of UN refugee chief Antonio Guterres and Jordanian Foreign Minister Nasser Judeh.

"This mission that we are sharing has a key objective. It is to draw attention to the international community to express a much more stronger solidarity with Syrian refugees and the host countries that have kept their borders open to all those fleeing the conflict," said Guterres.

According to Guterres, Jordan has taken in some 200,000 Syrians — the largest number in the region. The refugee chief acknowledged the sheer numbers are taking a toll on Jordan's economy and resources, stressing that the "camp needs massive international funding" and that its conditions were "still not acceptable."

The UNHCR in April promoted Jolie from serving as its goodwill ambassador to special envoy due to her exceptional work for the agency.

Jordan opened up the Zaatari facility for Syrians in July after long delaying a decision on whether to set up refugee camps, possibly to avoid angering Syrian President Bashar Al Assad's autocratic regime by showing images at his doorstep of civilians fleeing his military onslaught.

Jolie was also to visit Syrian refuges in Lebanon, Turkey and Iraq during the rest of her trip to the region.
