UNICEF: There's Been A 500% Increase In Refugee Children Travelling Alone.
Children's charity UNICEF is warning there's been a five-fold increase in number of refugee and migrant children traveling alone.
200,000 unaccompanied minors applied for asylum across the world between last year and the year before.
They accounted for 92 per cent of all children arriving to Italy by sea in 2016.
UNICEF is warning that smugglers and traffickers are exploiting children forcing them into slavery and prostitution.
