Supporting Syria: How has the world helped?

A year ago today, world leaders met in London to discuss how to help the millions of people affected by Syria's war.

A record $12bn (£9.6bn) was pledged and an ambitious target was set, that by the end of the 2017 school year all refugee children would have access to education.

Twelve months later there's still a great need for aid and around half of the children forced to flee Syria still aren't in school.
