The Syrian civil war began in March 2011. Since then, it is estimated to have killed at least 500,000 people, half of which are believed to be civilian casualties. The UN estimates that there are 7.6 million internally displaced people, with an estimated 6 million more who have fled the country.
The physical devastation in Syria is massive, with schools, hospitals and water treatment facilities destroyed. Meanwhile, an estimated 2.6 million children remain displaced inside Syria, while some 2.5 million children are living as refugees, in neighbouring countries.
Millions of refugees in Syria and countries bordering it are without real accommodation, many living in bombed out, derelict and squalid houses, only scraping together enough food each day to get by. Basic medical supplies, food and blankets are high in demand.
