More than 300,000 children traveled alone as refugees or migrants in 2015 and 2016 – a fivefold increase from 2010 – UNICEF officials said today, reflecting a surge in the number of people fleeing conflict and poverty. UNICEF officials hope that the data will move the seven leading economies to adopt measures at the G7 Summit in Italy that would protect refugee and migrant children. Meanwhile, the U.S. is putting pressure on the Italian government to drop the topic of migration from the G7 meeting later this month.
