The UK is to take in up to 3,000 more refugees - most of them vulnerable children - from the war-torn Syria region. Several hundred are expected to be resettled by April 2017, and the rest by 2020. The Government called the move the ‘largest resettlement programme for children in the world’. It is in addition to Prime Minister David Cameron's earlier pledge to take 20,000 refugees by 2020. The scheme will target unaccompanied children as well as those considered at risk of abuse and exploitation: these will include children threatened with child labour and child marriage. There are more than 4.5 million refugees across the region - half of them children in need of food, education and a home. The UN has warned that a whole generation of Syrian children is at risk.
