The 37-year-old actress, who is a United Nations Goodwill Ambassador, flew to the Middle East for the second time in three months to draw attention to the plight of those who have escaped Syria amid ongoing fighting between rebels and government forces, reported Sun online.
"The incredible compassion shown to these traumatised refugee families by the Jordanian border guards was extremely moving.
Jordan has welcomed the refugees even though it has placed a huge burden on the country.
"The international community needs to show more solidarity and to support Jordan and the other countries in the region who continue to keep their borders open," she said.
Medical staff kept Jolie updated about the condition of Syrian citizens and she was left horrified to hear of one young boy who had lost his leg.
"It was extremely upsetting to hear the story of an eight-year-old boy, who, upon arrival in Jordan, explained to doctors that he had asked his family to carry his severed leg along on the journey in hopes that it could be reattached.
"I'm sickened by how long and how bloody this conflict has become, devastating a nation and the lives of millions of innocent civilians, and threatening to destabilise the entire region...," she added.
