Two years ago, a group of children scrawled anti-government messages onto a wall in Syria's southern province of Dara'a.
This act of youthful rebellion landed the youngsters in jail. Their continued incarceration and a palpable sense of revolution in the Arab air led a few hundred local people onto the streets to protest. The crowd swelled and soon numbered thousands. Syrian security forces attempted to quell the protest with force, opening fire and killing four people.
The peaceful protests that followed were met with violence, escalating into a civil war that is now threatening to engulf the region. Refugees began spilling over the borders into neighbouring safe havens Turkey, Iraq, Lebanon and Jordan. Record numbers of Syrians are fleeing their homeland, with around 8,000 leaving every day.
Last week, the number of registered refugees passed the million mark. It now stands at over 1,100,000. Half of those that have fled are children and UNICEF has issued a stark warning about a 'lost generation' of Syrian youth.
61 per cent of refugees are living in urban settings but hundreds of thousands are living in camps, with 150,000 in Jordan's Za'atari camp alone.
