The world's most admired woman, actress and humanitarian Angelina Jolie is reportedly planning to adopt a Syrian refugee child.

Jolie, Special Envoy of the UN High Commissioner for Refugees is under negotiations to adopt two-year-old Syrian boy Moussa, the Sydney Morning Herald reported.

"Angelina heard about him from a translator and she was obviously upset, but Moussa was just beaming from ear to ear and when he saw she was wiping tears from her eyes. He toddled up to her and gave her a hug and it was a very emotional moment and everyone was suddenly laughing and smiling," an anonymous charity worker told the Sydney Morning Herald.

The charity worker also added that Jolie kissed the child on his head. And from then on, the two became inseparable for the entire duration of the actress' visit.

Jolie also went to a two-day interfaith conference in London, where she urged religious leaders including The Archbishop of Canterbury and William Hague, to raise awareness about sexual violence being used as a weapon of war, The Gospel Herald reported.

"Our most powerful assets are not our armies," she said. "They are our values. As faith leaders you are advocates for the values of compassion, tolerance, justice and reconciliation."

"We have to speak more loudly than those preaching hatred as religion. I believe we can," she said, adding that the use of sexual violence in war is "fuelled by impunity."

As a solution, Jolie suggested that they help lift the stigma attached to rape and sexual assault, raise awareness of the issue of sexual violence being used as a weapon of war, confront those who seek to use religion to justify sexual violence, and to demand justice for victims.

At the same time, the Unbroken director spent time at the Khanke refugee camp in Dohuk, where around 20,000 refugees driven from their homes by the Islamic State militant group seek solace.

She told The New York Times, "I have visited Iraq five times since 2007, and I have seen nothing like the suffering I'm witnessing now. For many years I have visited camps, and every time, I sit in a tent and hear stories."

Not one to lose hope, Jolie tried to inspire all those she encounters, but she was at a loss for words during this trip. "I try my best to give support. To say something that will show solidarity and give some kind of thoughtful guidance. On this trip I was speechless," she said.
