Eight years ago this week, 15 Syrian teenagers were detained and tortured for spraying anti-government graffiti on a school wall.
That was the beginning of an uprising that led to a civil war, which continues today.
The conflict has killed an estimated 560,000 people and created nearly six million refugees.
The UN and the European Union are holding a donor conference in Brussels to raise nine billion dollars for humanitarian assistance.
With the war now entering its ninth year, what does the future hold? And what hopes are there for peace?
