The Syrian civil war began in March 2011. Since then, it has killed at least 250,000 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.
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.
