30,000 migrant children disappeared in Europe between 2014 and 2017

In early 2016, Europol's top official Brian Donald told British newspaper "The Observer" that at least 10,000 unaccompanied migrants and refugee children have disappeared since 2014 after arriving in Europe. At the time, Donald stated that it would probably be more than 10,000 children and that this figure would be a "conservative" figure. Meanwhile, the European Migration Network, which is funded by the European Union and coordinated by the European Commission, estimates that 30,000 children traveling alone have disappeared between 2014 and 2017.
