"People talk about the refugees in Jordan or Lebanon, but most refugees are inside the city," said Touma. "All around Aleppo is war and more and more people are coming to the center."

"The center is so crowded, you can't imagine how many people are living in the city."

"When people do programs for refugees, they give them food and medicine, but not culture or anything to keep them busy.

"It's very important to everybody that there's heart in society still alive and that they still have some hope.

"These are people who have had to leave their homes, who have never been to a gallery before and now they are turning up to do art and see art.

"Now about 500 people have taken part in Art Camping. Not altogether, but different people have done different workshops."
